Microgrid Development Model and Control Strategy for Dual Carbon Target

Abstract

In recent years, in the face of China's increasingly serious environmental pollution and energy structure problems, the country has proposed the double carbon target of "peak carbon" by 2030 and "carbon neutral" by 2060, and microgrids, as a kind of small-scale power generation and distribution system with economy and environmental protection, can better absorb distributed energy. In the context of the dual carbon target, it is important to study the development mode and control strategy of microgrids energy. This paper firstly elaborates the advantages of combining microgrid and distributed energy, divides microgrid into grid-connected microgrid and stand-alone microgrid according to the operation mode, and gives the mathematical model of distributed energy. Based on the above, this paper studies grid-connected and stand-alone microgrids. Additionally, single-objective and multi-objective models under different strategies have been presented. The single-objective model aims to minimize operating costs, while the multi-objective model aims to minimize operating costs and carbon emissions simultaneously. Genetic algorithms have been employed to solve this problem, and MATLAB simulations have been used to analyze the models. The results of the simulations demonstrate that this strategy can significantly reduce carbon emissions with only a marginal increase in costs, thus validating the correctness and effectiveness of this approach.
