Virtual power plant optimal scheduling method considering electricity-to-gas coordination

Abstract

The invention relates to the technical field of virtual power plant optimization, in particular to a virtual power plant optimization scheduling method considering electricity-to-gas coordination, which comprises the following steps: introducing a carbon capture power plant electricity-to-gas gas unit coordinated operation framework into a virtual power plant, and constructing a virtual power plant system; performing combined scheduling operation of a carbon capture power plant, a waste incineration power plant and wind and light in a virtual power plant, optimizing a virtual power plant system by taking the carbon capture power plant and the waste incineration power plant as controllable units, and establishing a virtual power plant optimal scheduling model; and solving the virtual powerplant optimal scheduling model by adopting a reverse cotangent composite differential evolution algorithm. CO2 captured by carbon can be used as an electricity-to-gas raw material, and generated natural gas is supplied to a gas unit; and the carbon capture energy consumption and the flue gas treatment energy consumption are subjected to load transfer through combined scheduling so as to stabilizerenewable energy fluctuation, so that the wind power photovoltaic is indirectly schedulable and is flexibly utilized, and internal resources are more effectively utilized.

Description

technical field [0001] The invention relates to the technical field of virtual power plant optimization, in particular to a virtual power plant optimization scheduling method considering power-to-gas coordination. Background technique [0002] As the greenhouse effect and energy depletion caused by the use of fossil energy become increasingly prominent, the development of a high-proportion renewable clean energy network has become a global consensus. In 2019, my country's abandoned wind and solar power amounted to 16.9 billion and 4.6 billion kWh respectively, and the peak-to-valley difference in electric load was indirectly increased due to wind power grid connection. In response to this problem, the "13th Five-Year Plan for Electric Power Development" pointed out that multi-energy Complementarity is an important means to improve the capacity of renewable energy consumption. At present, how to improve the utilization rate of renewable energy and enhance the coupling between...
