Modeling and Control Of Grid-PV-SMES System

Today, storage energy strategy can be considered as one of the important topics to overcome the production outages and electricity shortages. So, the present paper shows a novel power system equipped by storage system based on SMES (Superconducting Magnetic Energy Storage). The SMES can stores energy without losses and can generates it based on demand/consumption or fluctuation of load/productions. The proposed SMES is charged using PV system, then the storage energy is injected into power system, the SMES control strategy is based on PI controller. However, the DC-DC boost is controlled by PID classical controller. Simulation has been carried out for different scenarios: variable irradiation, variable load. Obtained results show that the developed system operates perfectly during all scenarios (charging, standby, discharging), also the equality of consumption and generated power is always guarantee. Hence, SMES can improve the performances of power system under hard conditions.
