Combined Optimal Dispatching of Wind-hydro-thermal Power System with Wind Power Priority in Accessing to Power Grid
摘要
Abstract
Taking wind power priority in accessing to the power grid, the minimum total coal consumption cost of the thermal power generating unit and fluctuation amount of output of the thermal power generating unit as targets, this paper establishes a multi-objective combined optimal dispatching model for wind-hydro-thermal power system.By means of heuristic search, it determines the thermal power generating unit participating in dispatching in every dispatching time frame so as to avoid frequent startup and stop of the unit and system capacity redundancy.By introducing differential evolution (DE) algorithm, it improves deficiencies of existing particle swarm algorithm (PSO), and a typical 10-machine testing system is used to verify superiority of DE algorithm.Finally, simulating calculation on one regional power grid verifies reasonability of the proposed dispatching model and validity of the solution algorithm.关键词
