Optimized operation of micro grid electric heating integrated system based on PMV

Abstract

The characteristics of wind power, such as peak inversion, lead to serious wind abandonment in heating season. With the implementation and use of the heat storage electric boiler (HSEB), the utilization rate of wind power can be effectively improved by establishing the electric heat combined operation system with the HSEB. When the thermal comfort of human body is considered, the heat load will be changed into elastic range, and the regulation range of heating unit will be increased. Based on the analysis of the heat transfer state of the house on the user’s side, the relationship model between the outdoor temperature and the indoor heat supply is established in this paper. On this basis, the micro grid electric heating comprehensive system with the HSEB is constructed. Taking the minimum operation cost of the system as the objective function, the economic optimal operation model of the micro grid electric heating system based on PMV is established. The feasibility of the four schemes is verified by an example. The results show that the micro grid electric heating system based on the PMV contained HSEB can accommodate the abandoned wind power, reduce the fuel cost and reduce the environmental pollution on the premise of ensuring the indoor comfort, which has a good application prospect.
