Research On Micro-Grid Resources Planning Based On Game Theory Considering Carbon Trading

The appearance of carbon trading market is expected to replace clean energy subsidies to promote the development of clean energy in microgrids.As a new means of accelerating the adjustment of energy structure,the impact of carbon trading should be taken into consideration in the planning and configuration of micro-grid.However,under the background of increasingly open power market,the traditional unified planning and centralized distribution mode of development are no longer suitable for open market environment.The competition among the micro-sources makes the investment decision-making and resource allocation change to non-cooperative game.In this paper,we use the best response method to iteratively solve the Nash equilibrium of multivariate subjects in game competition,and study the effect of the introduction of carbon emission rights trading market on the micro-source game planning under different micro-grid operating modes.In this paper,the working principle and mathematical model of wind power,photovoltaic,micro gas turbine and energy storage in the structure of microgrid are described in detail.Taking into account the micro-power output and the micro-grid operation constraints,we choose minimum amount of discarded electricity and lack of power as the main objective of the optimization strategy to obtain annual cost and benefits of micro-grid resources under the three modes of micro-grid islanding operation,one-way networking.With the goal of maximizing the net income of each micro-source,the decision-making interaction between micro-grid resources under market conditions is simulated based on Particle Swarm Optimization(PSO),and the micro-grid resources allocation is obtained at the equilibrium point of the game.We introduce the carbon market environment in the process of simulating market conditions and consider the carbon trading as the cost of revenue into the annual cost benefits of micro-grid resources.Under the different operation modes of micro-grid,we compare the allocation and income in the context of carbon trading and environmental governance,it is verified that the introduction of carbon trading can enhance the utilization rate and profit value of renewable energy.Through the analysis of the calculation results,we explore the impact of different carbon prices on the allocation and income trends,and summed up the role of carbon trading prices on the market rules.
