Abstract: Systems and methods for controlling the temperature of an energy storage system are provided. More specifically, a time period of increased battery temperature attributable to, for instance, charging or discharging of the battery can be identified. A control system can be used to reduce the ambient temperature of a space associated with the battery energy storage devices in the time period prior to or immediately before the period of increased battery temperature. The ambient temperature can be maintained at a nominal ambient temperature at other times.

Abstract: Systems and methods for controlling an energy storage system to provide for delivery of multiple grid services are provided. Grid service requests can be categorized into a plurality of priority tiers. Power demands associated with the grid service requests can be allocated to enforce the prioritization scheme of the priority tiers. For instance, power demands associated with grid service requests in higher priority tiers can be given preference over power demands associated with grid service requests in lower priority tiers. Multiple grid service requests can be categorized within the same priority tier. In addition, the energy storage system can be controlled not only give priority to grid services requests categorized in the higher priority tiers, but also to manage the state of charge of the system to ensure that there is sufficient reserve capacity to meet power demands of the grid service requests categorized in the higher priority tiers.
Abstract translation: 提供了用于控制能量存储系统以提供多个电网服务的传送的系统和方法。 网格服务请求可以分为多个优先级。 可以分配与网格服务请求相关联的电力需求，以执行优先级的优先级排序方案。 例如，与更高优先级中的网格服务请求相关联的电力需求可以优先于与较低优先级中的电网服务请求相关联的功率需求。 多个网格服务请求可以在同一优先级层次中进行分类。 另外，可以控制能量存储系统，不仅优先考虑分类在较高优先级的电网服务请求，而且还要管理系统的状态，以确保有足够的备用容量来满足电力需求 网格服务请求分类为较高优先级。

Abstract: Systems and methods for controlling an energy storage system are provided. In one embodiment, a method for controlling an energy storage system includes receiving a power demand associated with a grid service operation for an energy storage system and accessing data indicative of a time shift for responding to the power demand. The method includes implementing the time shift in the power demand to obtain a time shifted power demand; and controlling the charge or discharge of one or more energy storage devices in the energy storage system based at least in part on the time shifted power demand.

Abstract: Systems and methods for controlling power distribution are provided. The method includes receiving a power command, wherein the power command requests a discharge from one or more BESS units, and wherein the one or more BESS units are housed in one or more temperature controlled rooms. For each of the one or more temperature controlled rooms, a lowest energy remaining of the one or more BESS units in the temperature controlled room is determined; a low threshold is determined based on the determined lowest energy remaining and a floor; a limit is determined based on the determined low threshold; and the limit is assigned to each of the one or more BESS units housed in the temperature controlled room. The method includes causing the power command to be at least partially satisfied by the one or more BESS units based on the assigned limits.

Abstract: The present disclosure is directed to a system and method for controlling an energy storage system. The energy storage system includes a plurality of battery strings connected in parallel with the battery strings having a plurality of batteries connected in series. The method includes determining, via a controller, one or more operating parameters of the energy storage system. The method also includes determining, via the controller, a maximum current rating of one or more of the battery strings. Another step includes estimating, via the controller, a voltage range for the one or more battery strings as a function of the one or more operating parameters and the maximum current rating. The method also includes dynamically controlling the one or more battery strings based on the voltage range so as to prevent over-current recharge or discharge of the parallel battery strings.
