The invention relates to an energy storage system and a control method, which can consume redundant electric quantity generated during photovoltaic power generation in time. Under conditions of scheduled outage and non-scheduled outage of a power distribution grind, the energy storage system can be automatically and seamlessly switched to an off-line working mode to guarantee uninterruptible power supplying of a load. The energy storage system consists of a PV array consisting of connecting multiple solar battery panels in parallel, a photovoltaic inverter, an STS intelligent switching cabinet, a double-stage energy storage converter for automatically switching direct current and alternating current, and a PC background control system, wherein the PV array converts generated direct current into alternating current through the photovoltaic inverter and transmits the alternating current to a bus, and at the same time, a power grid is connected into the bus; a circuit control switch is arranged between the power grid and the bus; the STS intelligent switching cabinet is arranged between the double-stage energy storage converter and a grid connected point of the bus; the double-stage energy storage converter is connected with an energy storage battery; the bus is further connected with an alternating current load; the PC background control system is in communication connection with the photovoltaic inverter, the double-stage energy storage converter and the circuit control switch respectively.
Description
Technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to an energy storage system and a control method. Background technique [0002] Photovoltaic power generation is a process in which solar energy is directly converted into electrical energy under certain conditions. During the conversion process, there is no pollution and noise. Therefore, as a clean, environmentally friendly and renewable distributed power generation method, it is vigorously promoted and applied in various countries. Sometimes the current generated by photovoltaic power generation cannot be completely consumed. In order to prevent energy waste, it needs to be stored for backup. However, the stored electric energy is often unable to be used in time or the efficiency of reuse is low. Summary of the invention [0003] The purpose of the present invention is to provide an energy storage system and a control method, which can not only absorb the excess electricit...
