摘要： An energy storage system includes a battery cluster, a direct current converter, a controller, and at least one power conversion system. The energy storage system includes at least one direct current branch. The direct current branch includes a battery cluster and a direct current converter that are connected to each other. The direct current converter performs direct current conversion on a direct current provided by the battery cluster. Each battery cluster includes at least two energy storage modules that are connected in series. The controller controls the first equalization circuit, to balance electricity quantities of battery modules in the battery cluster, and allocates operating power to the power conversion system and the direct current converter. In this solution, impact of bucket effect on the energy storage system is reduced, so that a battery capacity can be more fully utilized.

摘要： An exemplary power system includes a DC power bus and a photovoltaic system connected to the DC power bus. An energy storage system is connected to the DC power bus and stores energy injected to the DC power bus by the photovoltaic system. A power inverter is connected to the DC power bus and converts power between the DC power bus and an AC connected load. The power system also includes a control system that receives power system data from one or more sub-systems and devices connected to the DC power bus, and controls, in real-time, one or more of the power inverter and the energy storage system to act as a load on the DC power bus based on the received power system data.

摘要： A system in a vehicle includes a first winding section including first two or more windings and a second winding section including second two or more windings. Each of the second two or more windings corresponds to one of the first two or more windings of the first winding section. The system also includes an inverter including a high side switch and a low side switch corresponding to each of the first two or more windings. The inverter is coupled to a battery of the vehicle and boosts a voltage of a direct current (DC) charger during charging of the battery with the DC charger, converts alternating current (AC) from an AC grid to DC during charging of the battery with the AC grid, and converts DC to AC during supply of the AC grid by the battery.

摘要： A smart meter system is described for managing demand side electrical transactions with shifted demand in a smart grid. The smart meter controller uses non-cooperative game theoretic analysis for managing multi-periodic smart grid shifted demand. The problems of user based electricity demand, production, storage, and sales of energy to providers are addressed. The smart meter system described is used in the control of Home-Area-Network (HAN) or Wide-Area-Network (WAN) demand response management (DRM).
