The invention belongs to the technical field of power system power distribution network dispatching operation and grid management, and particularly relates to a wind-water-fire combined dispatching method based on wind power priority grid connection. The method comprises the following steps: firstly, obtaining wind power prediction power and load prediction power in one day by a dispatching center; secondly, establishing a target function and a constraint function by a wet season and a dry season; thirdly, adopting a particle swarm algorithm to solve a target function; and finally, according to an optimal solution, distributing output power between a hydraulic power plant and a heat-engine plant. The method fully considers the characteristics of big volatility and low cost of wind power grid connection, carries out analysis combined dispatching in two periods of the wet season and the dry season, adopts the particle swarm algorithm to carry out global optimization on a dispatching algorithm, obtains the optimal solution to carry out power distribution dispatching, and realizes the full utilization of renewable energy sources and economic benefit maximization.
Description
technical field [0001] The invention belongs to the technical field of power system distribution network scheduling operation and power grid management, and in particular relates to a combined wind, water and fire scheduling method based on wind power priority connected to the grid. Background technique [0002] With the continuous growth of energy demand, the gradual depletion of fossil fuel resources, and the increasingly prominent environmental problems, wind power generation, as one of the most economically promising power generation methods among renewable energy sources, is increasingly favored and valued by people. Different from traditional power generation, the output power of wind power is intermittent and random, which brings new challenges to power system dispatching. After the wind power is connected to the grid, the combined optimal dispatch of wind, water and fire in the power system is a subject with significant economic benefits but relatively complex calcul...
