The present invention is a multi-energy complementary coordinated power generation dispatching method based on wind-solar-water-fire-storage combined system, which is characterized in that it includes the following steps: firstly, using the improved Markov chain method to simulate the time sequence of wind power / photovoltaic output; secondly, to determine the load Demand, the minimum economic output of thermal power units, and the boundary conditions of forced output of hydropower plants, and calculate the feasible region of renewable energy power generation operation; then prioritize wind power and photovoltaic power generation in the feasible region of renewable energy Plan to formulate a hydropower dispatching strategy; finally, comprehensively consider the operating cost of thermal power units and energy storage operating costs considering life loss, and aim at the minimum total operating cost of thermal power units and energy storage within the dispatching period, formulate a joint dispatching strategy for thermal power units and energy storage, And the particle swarm optimization algorithm is used to solve the corresponding optimization objective function, and then the scheduling strategy of the combined system of wind, water, heat and storage is obtained. The method has the advantages of being scientific and reasonable, simple and applicable.
Description
technical field [0001] The invention relates to the field of multi-energy complementary coordinated power generation scheduling in a power system, and is a multi-energy complementary coordinated power generation scheduling method based on a combined system of wind-solar, water, fire and storage. Background technique [0002] In recent years, the installed capacity of renewable energy power generation has grown rapidly. By the end of 2017, the global installed capacity of wind power, photovoltaic and hydropower reached 539.58GW, 403.5GW and 1267GW respectively. Compared with fossil fuel-burning thermal power, wind power and photovoltaic power generation can reduce environmental pollution and improve the energy structure, but the output of wind power and photovoltaic power is volatile. With the rapid development of wind power and photovoltaic power, it is difficult to balance the supply and consumption of wind power and photovoltaic power. The drawbacks of the solar system hav...
