Abstract

Considering the randomness and undispatchable characteristic of distributed photovoltaic power generation and also for solving the problem that the access of large-scale distributed photovoltaic power grid has a great impact on the safe and stable operation of power grid in bay area

a kind of energy optimal dispatching strategy for joint dispatching of combined energy storage power station is proposed in this paper. The all-vanadium liquid flow battery is used as the energy storage mode of the energy storage power station. The minimum variance of net load and the minimum operating cost of power generation in bay area are selected as the objectives and the optimal dispatching model is set up by the use of modified OBL-PSO algorithm. Finally

the effectiveness of the optimal dispatching strategy is verified by the simulation and analysis.
