Product description.
ESS offers small communities, industrial centers and commercial building complexes a turnkey
microgrid hardware and software system that typically provides the following results:
(1) 20 percent reduction in carbon emissions
(2) 20 percent increase in efficiency of delivering power to critical services in the community
(3) 98 percent reduction in power outages to critical facilities in the community
产品描述
ESS为小型社区，产业园区和商业建筑提供复杂智能电网钥匙硬件和软件程序，通常会有以下结果：
(1) 减少20%的碳排放量
(2) 社区提供关键服务的效率提高20%
(3) 社区关键设施电力中断的概率减少98%
ESS accomplishes this by aggregating local load and distributed sources into microgrids that can
seamlessly switch in/out of the power grid in less than ten cycles. The system is capable of
integrating 100 percent solar PV, 100 percent electric vehicles and their respective charging
stations, batteries and other renewable sources (hydro and biofuel cells) into an energy surety
system providing uninterruptable power to critical loads inside the microgrid while providing a
rapid financial return to the owner.
ESS通过整合本地负载和分布式资源到微电网，可以无缝切换输入/输出电网，在不到10个周期来完成这一点。该系统能够整合100％的太阳能光伏发电，100％的电动汽车和各自的充电站，电池和其他可再生能源（水电和生物燃料电池）转换为能源保障系统提供不间断电源关键负载的微电网内同时提供快速的财务回报给业主。
The system includes proprietary measurement devices to implement the control system. Standard commercial relays are used to operate breakers inside the system. The new measurement based systems include easy to install high speed time synchronized measurements of voltage and current magnitude and angles. This information is used in real time to optimize the performance of the system and respond to external disturbances.
该系统包括专有的测量装置来实现控制系统。标准商业继电器被用于在系统内操作的断路器。新的测量为基础的系统包括易于安装的电压和电流的幅值和角度的高速时间同步测量。此信息被用于实时优化系统的性能和对外部干扰的响应。
One of the commercial drivers for increasing use of microgrids is based on recommendations in
the recent USA National Climate Assessment report released on May 6, 2014. The policies presented will help mitigate climate change. Our goal is to deliver carbon free microgrids while
providing frequency and voltage support when connected to the area power system at the lowest
possible cost to the end user. Other ancillary services to the area power system are included.
一个商业驱动程序越来越多地使用微网是基于最近在2014年5月6日公布的美国国家气候评估报告中的建议，其中提出的政策将有助于缓解气候变化。我们的目标是当以尽可能低的成本向最终用户连接到该区域的电力系统中提供频率和电压的支持的同时实现无碳排放。该地区电力系统等配套服务设施也包括在内。
“Therefore, the mitigation section of this assessment (Ch. 27: Mitigation) noted the importance of research to understand and develop emission reductions through: 1) identifying climate and global change scenarios and their impacts; 2) providing a range of options for reducing the risks to climate and global change; and 3) developing options that allow joint mitigation-adaptation strategies, such as buildings that are more energy efficient and resilient to climate change impacts.”
“因此，本次评估的缓解部分（27章：缓解）指出研究的重要性和发展减排需要通过：
1）确定气候与全球变化情景及其影响;
2）提供一系列减少对气候和全球变化的风险选项;
3）制定方案，允许合资减缓，适应战略，如建筑物更节能和适应气候变化的影响。“
The Energy Surety System is packaged in a substation hardened rack similar to that shown in the attached photo (a prototype of this system has been operating at UCSD for several years):

The system includes accurate GPS time based redundant computers meeting NERC Cybersecurity requirements requiring that no data be lost when the software is shut down for security or upgrade patches.
该系统含有符合NERC的网络安全要求的冗余计算机上的精确的GPS时间，即当系统为了安全和升级需要关闭时没有数据会丢失。

能源保障系统的基本结果为导向的产品包括：
(1) Commercial building microgrids
A turnkey system than includes, rooftop solar, battery, other energy source such as micro turbine or fuel cell and HVAC3 Agent control system and a curtailment contract with local Utility companies. Ancillary services would also be sold including local frequency regulation, voltage regulation, under frequency load shed, power export control. The ROI is from the services contract with the utility, per FERC Order 755 (Pay for performance). The services offered to the Utility could include: instantaneous curtailment, load shedding, under frequency load shedding, autonomous frequency control and local voltage control. The system includes the UBET4 notification system that uses the data model of the building HVAC system to automatically send emails to the building facility manager when the energy performance of a room exceeds standards. This advice is expected to lower the overall building energy consumption by 5 to 10 percent.

An energy storage and control system will be offered. This will be connected directly to a four quadrant inverter supporting control discharging and charging of the battery into a microgrid or the area power system. The control system will include the new wireless PMUs and the decoupled frequency and voltage controller. The goal is to sell into the emerging mandated energy storage market with added feature of ESS decoupled control technology. The system would autonomously regulate local frequency and voltage by simultaneously adjusting real and reactive power flow from the battery.
