Operation control strategy of load aggregator based on new energy consumption in power grid

Abstract

Abstract Managing the scattered small and medium-sized load by the existing ternary market model of regenerative electric heating is difficult. In this paper, the load aggregator is introduced on the basis of the traditional ternary market, transforming the existing ternary market model into the quaternary market transaction mode of new energy, power grid, load aggregator and regenerative electric heating users. The coupling relationship of four parties’ interests is studied for the win-win solution limited by the goal of obtaining the maximum income and assuming the minimum risk. A case of Northeast China is carried out and the results show that the maximum profit point is 0.5 yuan/kWh, 0.3 yuan/kWh and 0.1 yuan/kWh respectively.
