    Abstract: A message bus is utilized for energy management/control. The publish/subscribe message bus present between site gateways, a central server farm, and other entities, facilitates exchange of messages pertaining to management and control of power generation and/or storage. On-site publishers/subscribers can include, e.g., PV inverters, battery devices, energy meters, etc. Non-site specific publishers/subscribers can include, e.g., web clients, database servers (for logging), and various server components of the message bus. Messages exchanged between publishers and subscribers can include control messages (e.g., begin charging battery X) and measurement messages (e.g., the current charge of battery X is Y). Embodiments may implement logic at a site gateway prioritizing transmission of messages to local site devices. Thus where a gateway cannot simultaneously transmit device control messages and device data acquisition messages (e.g., due to processing burden or congestion), site gateway logic can prioritize transmission of the control messages over the locally-generated data acquisition requests.

    Abstract translation: 消息总线用于能量管理/控制。 存在于站点网关，中央服务器场和其他实体之间的发布/订阅消息总线有助于交换关于发电和/或存储的管理和控制的消息。 现场发布商/订户可以包括例如光伏逆变器，电池设备，能量计等。非特定的发布者/订户可以包括例如web客户端，数据库服务器（用于记录）和各种服务器组件 消息总线。 在发布者和订户之间交换的消息可以包括控制消息（例如，开始为电池充电X）和测量消息（例如，电池X的当前电量为Y）。 实施例可以在站点网关实现逻辑，优先地将消息传输到本地站点设备。 因此，如果网关不能同时发送设备控制消息和设备数据获取消息（例如，由于处理负担或拥塞），则站点网关逻辑可以通过本地生成的数据获取请求对控制消息的传输进行优先级排序。

    Abstract: Embodiments of the present technology may include a method to enable real-time data requests. The method may include subscribing to real-time data enable requests for a device on an energy generation (EG) network. The method may also include intercepting, from a requester, a request for real-time data for the device on an EG system within the EG network. The method may further include publishing a single request to the device to post a single measurement corresponding to the real-time data request. The single request may be published at less than or equal to a predetermined frequency for a request cycle that lasts for a predetermined duration.

    Abstract: Methods for controlling an energy storage device to reduce peak power demand at a site are provided. In one embodiment, load data corresponding to a load in a utility grid-connecting energy generation (EG) system is received. The load data may be sampled at a first predetermined interval, and the EG system may include an energy storage device. A load threshold level is received, and a discharge control signal is generated. The discharge control signal may be generated when the measured load is at or above the load threshold level. The control signal may be applied to the measured load for a second predetermined interval that is longer than the first predetermined interval.

    Abstract: Techniques for controlling a distributed generation management system may be provided. Real-time power generation information may be collected from sensors of energy generation systems that make up a grid of controlled systems. An aggregate real-time power generation requirement may be determined for the grid based on the real-time power generation information. Using the aggregate requirements, a power profile may be calculated for the grid that indicates a level of power generation for the grid. In some examples, a control signal to control power generation may be generated and provided to the controlled systems.

    Abstract: Certain embodiments include receiving load data from an energy generation (EG) system, where the load data is provided by a load meter, and where the load data corresponds to a predetermined time period. The predetermined time period may be during peak daylight hours (e.g., between 10 A.M. and 2 P.M). The method includes receiving EG data from the EG system, where the EG data corresponds to EG generation by an EG circuit over the predetermined time period, and determining if an inverse relationship exists between the load data and EG data. The method includes determining that the load meter is installed upstream from the EG circuit if an inverse relationship between the load data and EG data exists, and determining that the load mater is installed downstream from the EG circuit if an inverse relationship between the load data and EG data does not exist.

    Abstract: A computer-implemented method includes receiving power measurement data for a photovoltaic (PV)-based energy generation (EG) sites, determining if cloud cover is present over the EG site based on a difference between a present and historical power output for the EG site, calculating a density of the cloud cover over the EG site based on the present and historical power outputs, and controlling load characteristics of the EG site based on the determined presence and calculated density of the cloud cover. The density of the cloud cover is based on a percentage difference in power output between the present power output and the historical power output. A vector for the cloud cover can be determined based on movement of a detected storm system with a boundary defined by a location of a plurality of EG sites, or by a movement of the cloud density from one EG site to the next.
