Abstract
Aiming at a kind of multi-energy complementary isolated power system in Tibet ali area, which consists of photovoltaic (PV) station with storage device, hydro generator, and diesel generator, a new control strategy was presented. According to the power system characteristics, analyzed the new control strategy, it can realize the grid power output with zero steady-state error. In the DIgSILENT/PowerFactory simulation environment, building the multi-energy complementary isolated power system model and simulation based on the control strategy, the system can track the fast variation of the PV array output power or other output power. Two studied cases verify the control strategy.
