Hybrid Microgrid System
A microgrid hybrid energy storage solution consisting of energy storage unit and generator set is adopted. The energy storage system consisting of electrochemical energy storage and supercapacitor runs in parallel with the traditional internal combustion generating set. At peak load, the electrochemical energy storage unit + supercapacitor energy storage unit and the generator set jointly bear the load. At valley load, the generator set supplies power to the load and charges the energy storage unit at the same time, so that the generator set always operates in an efficient and fuel-efficient load rate range.
Product Introduction
Hybrid microgrid system is a system composed of generator set driven by internal combustion engine, battery pack, supercapacitor, and control system. It is mainly used to provide the required power source through the generator set driven by internal combustion engine, store the electric energy generated by the power source through the battery pack and output the electric energy required for operation alone or together with the power source, and stabilize the microgrid voltage through quickly charging and discharging of the energy storage system to cope with the impact load of the island power station, so as to reduce the configuration capacity of the power unit and improve the energy utilization.
