Abstract

Abstract:

The existing research achievements on the scheduling strategy of renewable energy power generation are mostly for wind power, solar power or wind-photovoltaic generation system, wind-hydro generation system, but less involve wind-photovoltaic-hydro hybrid generation system. So this paper proposed the scheduling strategy for the hybrid generation system. The lowest-cost optimization model was built under two operation modes: isolated and grid-connected operation, with considering investment, operating costs of system and environmental governance. Then, this paper proposed the scheduling strategy of the hybrid generation system to realize the best configuration of output power of the three resources, whose feasibility was verified by related simulation results. The results show that the optimal operation and scheduling strategy can assess the economical performance of the system under different operation modes, thus improve the reliability and flexibility of the hybrid system.

Key words: wind-photovoltaic-hydro hybrid generation, optimization model, scheduling strategy, simulation model
