Abstract

A regional comprehensive energy system configuration optimization method based on photovoltaic consumption comprises the steps that a regional comprehensive energy system basic framework based on photovoltaic consumption is established according to regional electricity, cold and heat load requirements; constructing a regional comprehensive energy system capacity configuration optimization model bytaking the highest economy, the highest system energy supply reliability and the lowest light abandoning rate of the system as target functions; power generation strategies are set to be photovoltaicpower generation, a combined cooling heating and power supply unit, an energy storage unit and an external large power grid energy supply unit in sequence; mATLAB language programming is used for realizing regional comprehensive energy system configuration optimization, optimal capacity configuration, namely the configuration number of all units, is obtained, and configuration power is obtained through calculation; meanwhile, annual operation results which comprises system energy supply composition, photovoltaic consumption conditions and energy supply interruption conditions are output. According to the method, the purpose of effectively promoting photovoltaic consumption on the basis of ensuring the energy supply reliability can be achieved, and the photovoltaic utilization rate and theoptimization efficiency of regional comprehensive energy are effectively improved.

Description

technical field [0001] The invention relates to the field of configuration optimization of comprehensive energy systems and the field of photovoltaic power generation, in particular to a configuration optimization method of regional comprehensive energy systems based on photovoltaic consumption. Background technique [0002] With economic development and social progress, the demand for energy is increasing rapidly, and energy supply is in short supply, which puts forward higher requirements for energy utilization efficiency and utilization methods. Traditional energy systems are independent of each other during planning and operation, such as power supply systems, heat supply systems, etc., and energy utilization is single. The integrated energy system couples and utilizes various energy sources such as electricity, cooling and heating, and natural gas, coordinates and optimizes each link, realizes the efficient use of energy and meets the needs of multiple types of energy s...
