Scheduling strategy of hybrid Wind-Photovoltaic-Hydro power generation system

Wind-Photovoltaic-Hydro hybrid generation is a new multi-energy hybrid system combined with respective advantages of wind energy, solar energy and hydropower. This paper builds the lowest-cost optimization model, considering investment, operating costs of system and environmental governance as well as two operation modes, isolated and grid-connected operation, and proposes the scheduling strategy of the hybrid generation, with the aim to realize the best configuration of output power of the three resources. Simulation results indicate that the optimal operation and scheduling strategy can assess the economical performance of the system in different operation modes, thus improve the reliability and flexibility of the hybrid system.
