Abstract :
In promotion of the new energy policy, the large-scale expansion of constructions of the wind and solar power is developing in China, whose random high-power electric energy fluctuation causes huge shock to the power grid. Confronting this important problem of the power system safe operation, it is really top urgent to build a feasible solution to develop the large-scale new energy. Therefore, this paper raises a distributed generation system (DGS) based on various renewable energy resources, adopting a small-sized combined generation equipments of unit capacity 100 kW max with wind, solar and biogas energies, and super capacitor and battery storage devices, which builds and installs near to the local loads center to supply it optimally in stable and safe, high reliability and less feeder loss mode. The operation performance of the demonstration project shows: the DGS based on various renewable energy resources is an effective and feasible approach for its large-scale and efficient utilization purpose because of its particular distribution characteristics, direct power supply to the local loads and its little influence to the grid.
