中國儲能網(wǎng)訊：儲能已成為當(dāng)今電網(wǎng)的重要組成部分。由于可再生能源的發(fā)電高峰期不同于能源需求高峰期,因此將部分過剩電力存儲以備后用,這種場景對未來的清潔能源電網(wǎng)來說是不可或缺的部分。鑒于此,建立大規(guī)模的儲能設(shè)施網(wǎng)絡(luò)已成為優(yōu)先事項,且每年都在增加。這些儲能系統(tǒng)每個都獨一無二,具有自己的配置方案和管理挑戰(zhàn)。過去,每一個這樣的儲能設(shè)施都需要一個專門創(chuàng)建的管理系統(tǒng),這是一個既費時又費錢的過程。需要一個可以在許多不同儲能環(huán)境中均可適用的能源管理系統(tǒng)。FlexGen的HybridOS能源管理軟件正是針對這一需求而創(chuàng)建的。從這個起點出發(fā),FlexGen團隊持續(xù)進(jìn)行創(chuàng)新,以提高平臺的實用性和性能,并適應(yīng)儲能運營商不斷面臨需求變化和新挑戰(zhàn)。儲能系統(tǒng)在現(xiàn)代的能源世界中越來越重要,因為它們能夠以各種方式存儲和管理能源。這些系統(tǒng)可用于存儲來自風(fēng)力、太陽能等可再生能源的能源,也可用于存儲來自傳統(tǒng)能源的能源。
Energy storage has become an essential part of today’s electrical grid. Since renewable energy production does not peak at the same time as energy demand, the storage of some of that excess energy for later use becomes an indispensable part of the clean energy grid of tomorrow, one that is growing closer to reality with every passing day. Given this necessity, the creation of a vast web of energy storage facilities has become a priority, with more coming online year over year. Each of these storage systems is unique, with its own configuration and set of challenges to manage. In the past, each of these facilities required a management system to be created specifically for that facility, a process that consumed both time and capital. An energy management system was needed that could be modified in many different storage contexts. FlexGen’s HybridOS energy management software was created in response to that need. From that starting point, the FlexGen team continuously innovates to improve the platform’s utility and performance, as well as to adapt to changing needs and new challenges that operators of energy storage face. Energy storage systems have become increasingly important in the modern world, as they are able to store and manage energy in a variety of ways. These systems can be used to store energy from renewable sources such as wind and solar, as well as from traditional sources.
適應(yīng)性
Adaptability
能源管理系統(tǒng)(EMS)是一個軟件和數(shù)字控制平臺,可實現(xiàn)對電池儲能系統(tǒng)(BESS)的監(jiān)控和控制。傳統(tǒng)上,每個BESS都會根據(jù)其特定配置和所使用的硬件類型創(chuàng)建一個定制的EMS。由于創(chuàng)建的系統(tǒng)針對性很強,因此最初的配置和硬件就此確定。FlexGen團隊在創(chuàng)建HybridOS時面臨的首要任務(wù)(和挑戰(zhàn))之一,就是需要一個不依賴于任何品牌或制造商的硬件的EMS。HybridOS的設(shè)計就是硬件無關(guān)的,這意味著它可以與設(shè)施運營商首選的任何類型的電池系統(tǒng)一起使用,而不必?zé)o限期依賴該制造商。
An Energy Management System (EMS) is a software and digital control platform that enables the monitoring and control of a Battery Energy Storage System (BESS). Traditionally, a bespoke EMS was created for each BESS, based upon its specific configuration and the type of hardware that was being used. As a result of the narrowly focused system that was created, that initial configuration and hardware were locked in. One of the first priorities (and challenges) that the FlexGen team faced in creating HybridOS was the need for an EMS that was not dependent upon any brand or manufacturer of hardware. HybridOS was designed to be hardware agnostic, meaning that it can be used with whichever type of battery system the operators of the facility prefer without having to be dependent on that manufacturer indefinitely.
真正靈活的EMS還需要能夠處理不同的配置。在電網(wǎng)層面,儲能的主要功能之一是儲存可再生能源生產(chǎn)高峰期(對光伏發(fā)電來說是下午)產(chǎn)生的額外功率載荷,并將其保留到能源需求最高時使用(通常是晚上)。一些系統(tǒng)純粹用于這一目的,稱為負(fù)載移位。針對其他儲能設(shè)施適用的系統(tǒng)網(wǎng)絡(luò)——有時地理位置分散,有時使用幾種儲能方式——需要相互協(xié)調(diào)以發(fā)揮其功能。還有一些可能是微電網(wǎng)(封閉電力系統(tǒng))的一部分,其管理中存在獨特的挑戰(zhàn)。一些儲能系統(tǒng)還有更廣泛的用途;它們可能提供不同的電網(wǎng)輔助服務(wù)。為了真正實現(xiàn)硬件無關(guān)和靈活性,HybridOS被設(shè)計為可適應(yīng)所有這些應(yīng)用場景。FlexGen的方法和實施對能源效率和能源消耗將帶來巨大利益并為公司和組織節(jié)省成本。
A truly flexible EMS needs to be able to handle different configurations as well. One of the primary functions of energy storage at the grid level is the storage of the excess power load produced during peak renewable energy production times (in the afternoon for solar power production) and preserving it for when the energy demand is the highest (usually in the evening). Some systems are used purely for that purpose, known as load shifting. Other systems are a network of storage facilities – sometimes separated geographically, sometimes utilizing several types of storage – that need to be coordinated with each other to serve their function. Still others may be part of a microgrid (an enclosed electrical system) that has its own unique challenges in management. And some energy storage systems are used for a wider range of purposes; they may offer different grid ancillary services. In order to be truly hardware agnostic and flexible, HybridOS was designed to be adaptable to all these use cases. FlexGen’s approach and implementation too energy efficiency and energy consumption will have mass benefits and save costs for companies and organizations.
創(chuàng)新實驗室
The Innovation Lab
為促進(jìn)HybridOS適應(yīng)各種儲能系統(tǒng)的過程,FlexGen創(chuàng)建了一個可調(diào)整以模擬客戶設(shè)施配置的虛擬和物理環(huán)境,稱為創(chuàng)新實驗室。該實驗室允許FlexGen團隊預(yù)測BESS的需求、測試EMS并在調(diào)試過程開始之前對其進(jìn)行故障排除。
To facilitate the process of adapting HybridOS to various energy storage systems, FlexGen created a virtual and physical environment that can be adjusted to mimic the configuration of a client’s facility, called the Innovation Lab. The Lab allows the FlexGen team to anticipate the needs of a BESS, test the EMS, and troubleshoot it before the commissioning process even begins.
因此,HybridOS在減少新站點投入運行所需的時間方面取得了長足的進(jìn)步。根據(jù)ERCOT(德克薩斯州獨立系統(tǒng)運營商)的數(shù)據(jù),其合作設(shè)施的平均調(diào)試時間為60天;FlexGen的平均調(diào)試周期為14天。這可能額外增加一個半月的運行時間,從而使該設(shè)施的投資能更快見效。
As a result, HybridOS has made great strides in reducing the time it takes to get a new site up and operating. According to ERCOT (Texas’s independent service operator), the average commissioning time among the facilities they work with is 60 days; FlexGen’s average commissioning period is 14 days. That is potentially an extra month and a half of operating time, allowing the investment made in that facility to see a return that much faster.
同樣,創(chuàng)新實驗室測試HybridOS在特定環(huán)境下的工作方式的能力,可縮短升級時間。團隊可以在實施前看到最新版本的軟件在設(shè)施中的運行情況。因此,升級所需的停機時間可以大大縮短。例如,10MW系統(tǒng)可以在不到一天內(nèi)完成升級。FlexGen團隊還根據(jù)其個別用電模式和預(yù)測幫助客戶選擇停機時間的最佳窗口,進(jìn)而增加生產(chǎn)力,為企業(yè)節(jié)省創(chuàng)造機會和技術(shù)。
Similarly, the Innovation Lab’s ability to test how HybridOS will work in a particular environment allows for the shortening of upgrade times. The team can see how the newest version of the software will work in a facility before putting it into effect. As a result, outage times required for an upgrade can be cut down dramatically. For example, a 10-megawatt system can be upgraded in less than a day. The FlexGen team also helps the client to choose the optimal window to take that outage time based upon its individual usage patterns and forecasting. Increasing productivity, creating opportunities and technology for business savings.
復(fù)雜問題簡單化
Making Complexity Understandable
任何能源管理系統(tǒng)(EMS)的目的都是使這些復(fù)雜系統(tǒng)可解釋和可管理。但是許多EMS在本應(yīng)清晰的地方是模糊的,數(shù)據(jù)和系統(tǒng)運行狀況的表示方式難以理解。有些需要由專門受訓(xùn)的人來編程功能。
The purpose of any Energy Management System (EMS) is to make these complex systems decipherable and manageable. But many EMSs are opaque where they should be clear, with difficult to understand presentations of data and system health. Some require functionality to be programmed by people specially trained to do so.
HybridOS持續(xù)發(fā)展的一個關(guān)鍵創(chuàng)新是高級用戶界面(UI)。UI提供了對電力系統(tǒng)的全面可視化,允許用戶實時監(jiān)控系統(tǒng)性能、能源使用和電池本身的健康狀況。簡單易用的UI允許沒有編程背景的人員控制系統(tǒng)操作。重要的數(shù)據(jù)點通過可理解的可視化方式(如圖表和圖形)輕松呈現(xiàn)。我們的目標(biāo)是提供經(jīng)理需要的信息、應(yīng)用程序和流程,以及提供資源和解決方案。
A key innovation in the continuing development of HybridOS is the advanced user interface (UI). The UI provides a comprehensive visualization of the power system, allowing users to monitor system performance, energy usage, and the health of the batteries themselves in real time. An approachable UI allows personnel without a programming background to control the operations of the system. Important data points are easily digestible, using understandable visualizations like charts and graphs. Our objectives are to provide the information, applications and the processes that meet the requirements managers need, as well as, providing the resources and solution.

Through advanced data analytics, HybridOS offers valuable insights, empowering users to make informed decisions regarding system optimization, maintenance, and performance enhancements. Clients report that the comprehensive analytics capabilities of HybridOS have become more valuable than looking at data through their SCADA systems.
市場檢驗
Market Presence
HybridOS演變過程中的一個重要部分是其在全國日益增長的市場中進(jìn)行檢驗。HybridOS現(xiàn)在可以在大多數(shù)市場上找到,尤其與ERCOT(德克薩斯州電力可靠性理事會)有著強大的聯(lián)系。HybridOS可通過電池電廠的調(diào)度實體適應(yīng)任何獨立系統(tǒng)運營商(ISO)。但在ERCOT中,HybridOS能夠直接與ISO的系統(tǒng)模型接口,允許將多樣的電網(wǎng)輔助服務(wù)納入其中,以擴大儲能設(shè)施可用的收入來源。這種能力也已在CAISO(加利福尼亞州的ISO)中開發(fā)出來,HybridOS的持續(xù)發(fā)展將是將這種能力擴展到其他ISO。
An important part of the story of HybridOS’s evolution is its growing presence throughout the country. HybridOS can now be found in most markets, with an especially strong connection to ERCOT (Electric Reliability Council of Texas). HybridOS is adaptable to any Independent Service Operator (ISO), through the battery plant’s scheduling entity. But in ERCOT, HybridOS is able to interface directly with the ISO’s system model, allowing for the incorporation of stacked grid ancillary services to expand the revenue streams available to an energy storage facility. This capacity has also been developed for CAISO (California’s ISO), and HybridOS’s continued evolution will be to expand that capacity into other ISOs as well.
支持參與電力市場多種輔助服務(wù)
Supporting Stacked Ancillaries
電網(wǎng)輔助服務(wù)是除了發(fā)電、輸電和儲能之外,電網(wǎng)穩(wěn)定性和可靠性所需的額外功能。HybridOS允許設(shè)施與其ISO協(xié)調(diào)提供一系列輔助服務(wù),允許站點運營商最大限度地提高投資回報。儲能站點可以提供的輔助服務(wù)取決于該設(shè)施的功能和當(dāng)?shù)啬茉词袌龅慕Y(jié)構(gòu),包括:
Grid ancillary services are the additional functions required for the stability and reliability of the grid beyond the production, transmission, and storage of power. HybridOS allows facilities to coordinate with their ISO providing a range of ancillary services, allowing site operators to maximize the return on their investment. The ancillary services that an energy storage site can provide depends on the capabilities of the facility and the structure of the local energy market, including:
頻率調(diào)節(jié)——儲能系統(tǒng)可以快速注入或吸收功率來幫助調(diào)節(jié)電網(wǎng)頻率。HybridOS允許它們在毫秒內(nèi)響應(yīng)頻率偏差,提供快速準(zhǔn)確的調(diào)節(jié)支持。
Frequency regulation – Energy storage systems can quickly inject or absorb power to help regulate grid frequency. HybridOS allows them to respond within milliseconds to frequency deviations, providing fast and accurate regulation support.
電壓控制——儲能系統(tǒng)可以通過注入或吸收無功功率來幫助調(diào)節(jié)電壓水平。通過動態(tài)調(diào)整其輸出,HybridOS使其能夠穩(wěn)定電壓并支持電壓控制功能。
Voltage control – Energy storage systems can help regulate voltage levels by injecting or absorbing reactive power. By dynamically adjusting their output, HybridOS enables them to stabilize voltage and support voltage control functions.
黑啟功能——一些設(shè)施可以幫助電網(wǎng)在停電后重新啟動。
Black start capability – Some facilities can help the grid restart in case of a blackout.
設(shè)施可以提供哪些輔助服務(wù)將取決于所涉及的硬件和配置以及當(dāng)?shù)豂SO的政策。但這些輔助服務(wù)對于電網(wǎng)的功能和彈性至關(guān)重要,并且通常會相應(yīng)進(jìn)行補償。當(dāng)前的輔助服務(wù)市場估值約為80億美元,預(yù)計到2031年將值得兩倍以上。
Which ancillary services a facility can provide will vary depending on the hardware and configuration involved and the local ISO’s policies. But these ancillary services are essential to the function and resiliency of the grid, and they are often compensated accordingly. The current ancillary services market is estimated at $8 billion and is expected to be worth more than twice that by 2031.1
經(jīng)過市場檢驗的領(lǐng)先性能
Proven Performance
創(chuàng)新帶來成果。HybridOS現(xiàn)在已經(jīng)成熟到在美國各個市場上證明其性能遠(yuǎn)高于行業(yè)標(biāo)準(zhǔn)的地步。全國收入最高的兆瓦設(shè)施運行HybridOS。該軟件的響應(yīng)速度比最嚴(yán)格的行業(yè)標(biāo)準(zhǔn)要快25,000倍。HybridOS在行業(yè)迄今為止最嚴(yán)峻的考驗之一德克薩斯大停電期間也證明了自己,2021年獲得99.7%的可用性。HybridOS的行動影響能源使用,其工具和操作超越公司部門,改善所有人的生活,正如新聞中看到的那樣。
Innovation yields results. HybridOS has now matured to a point that it has demonstrated performance far above industry standards in markets across the U.S. The facilities with the highest revenue per megawatt in the country are run on HybridOS. The software can respond 25,000 times faster than even the strictest industry standards require. HybridOS also proved itself during one of the harshest tests of the industry yet, when it passed through the Texas freeze in 2021 with a 99.7% availability rate. HybridOS actions impact energy use, its tools and operation reach beyond the company sector and improve everyone’s lives as seen in the news.
持續(xù)創(chuàng)新
Continual Innovation
可再生能源的激增及支持它的儲能設(shè)施使電力系統(tǒng)日益復(fù)雜。隨著清潔能源轉(zhuǎn)型的推進(jìn),這一趨勢只會加速。需要持續(xù)創(chuàng)新來應(yīng)對即將到來的挑戰(zhàn)。一個可適應(yīng)并可更新的系統(tǒng)會與時俱進(jìn),使儲能運營商能夠使其投資具有未來適應(yīng)性。
The proliferation of renewable energy and the energy storage facilities that support it make for an increasingly complex electrical system. That trend is only going to accelerate as the clean energy transition progresses. Continual innovation will be needed to deal with the challenges that are coming. An adaptable and updateable system that continues to evolve with the times allows energy storage operators to future-proof their investment.
一些即將到來的創(chuàng)新是可以預(yù)見的。如前所述,在更多市場繼續(xù)擴展和與更多ISO的接口能力是HybridOS的可預(yù)見發(fā)展。最近在用戶界面方面取得的巨大飛躍也將繼續(xù)發(fā)展和改善用戶體驗。正在開發(fā)的數(shù)字孿生能力也將提供更大的監(jiān)控、診斷和故障排除功能。
Some of the coming innovations can be anticipated. As mentioned, the continued expansion into more markets and interfacing capability with more ISOs are a foreseeable evolution in HybridOS. The recent giant leap forward in UI will continue to evolve and improve the user experience. A digital twin capacity that will provide even greater monitoring, diagnostics, and troubleshooting capabilities is also in development.
有些變化是無法預(yù)見的。世界從未經(jīng)歷過目前這樣的能源轉(zhuǎn)型。如果要最大限度減少氣候變化的影響,電池儲能系統(tǒng)就是必需的,但圍繞這些設(shè)施的世界和市場將以不可預(yù)測的方式發(fā)生變化。HybridOS已經(jīng)發(fā)展到滿足客戶的需求,并將繼續(xù)這樣做。持續(xù)創(chuàng)新將使FlexGen和HybridOS能夠支持發(fā)電行業(yè)應(yīng)對未來的挑戰(zhàn)。
Some of the changes ahead cannot be anticipated. The world has never experienced the type of energy transition it is currently undergoing. The need for battery energy storage systems is a certainty if the world is to minimize the effects of climate change, but the world – and the market – will change around those facilities in unforeseeable ways. HybridOS has evolved to meet the needs of its clients and will continue to do so. Ongoing innovation will allow FlexGen and HybridOS to support energy generation as it responds to the challenges ahead.
