Transaction model and energy management optimisation method of rural microgrid

ABSTRACT Owing to the wide distribution of rural areas, the construction of power facilities is not perfect, which poses a great challenge to the power supply stability of the rural power grid. As an important supplement, the microgrid (MG) plays a complementary role in improving the power supply quality. However, the addition of the MG increases the complexity, and how to balance the interests of the participants has become a substaintial problem. Based on the analysis of the power consumption characteristics of rural residential, agricultural and industrial areas, a game relationship model between MG operators and power users is established, and the overall optimal strategy is obtained in this paper. For consumers, it can effectively achieve the effect of ‘peak shaving and valley filling’ and reduce the cost of electricity. For MG operators, it can improve the consumption rate of renewable energy and increase revenue.
