Economic and Social Benefit Model and Optimization under Gas and Photovoltaic Complementary Power Generation Mode

It is of great significance to establish the benefit model of gas and photovoltaic power generation for evaluating the feasibility and benefit of power generation projects. Aiming at solving the problem of independent analysis of economic and social benefits in the benefit model, this paper proposes an economic and social benefit model under the mode of gas and photovoltaic complementary power generation, which optimizes the scheduling of generating units. In this paper, firstly, aiming at solving the problem that the economic benefit and social benefit are separated in the model, the social benefit model is established by using the emission characteristics of gas and photovoltaic power generation units. The social benefit of the model is converted into economic value by life table method and combined with economic benefit to form the economic and social benefit of the power generation model. Then to solve the problem that the standard particle swarm optimization (PSO) algorithm is difficult to jump out of the local optimum, and the adaptive weight is improved. Finally, the model is validated with the measured data, and the results show that the model can achieve higher economic and social benefits.
