Abstract
With the large-scale integration of new energy, the obstruction of new energy consumption is prone to occur often during peak-down periods with a low load and high output of new energy. It is urgent to mobilize controllable load shifting through compensation mechanisms to achieve the goals of peak shaving, valley filling, and promotion of new energy consumption. This study constructs a framework of auxiliary service market and compensation mechanism for power shift between new energy power generation enterprises and controllable load enterprises. Secondly, aiming to achieve the principle of revenue balance between new energy power generation enterprises and controllable load enterprises, a quantity and price compensation model based on the particle swarm optimization algorithm is proposed. Then, under the principle of determining the compensation order of different controllable load enterprises through comprehensive evaluation and formulating differentiated compensation prices one by one, a compensation method and process for controllable load enterprises to shift have been established. Finally, through a case analysis, compensation prices for five types of controllable loads were formulated, with values ranging from 99.36 to 197.41 CNY/MWh. This increased the compensation for controllable loads on the basis of the original peak-valley price, verifying the feasibility of the method described in this study.
