China currently faces with both challenges of renewable energy consumption difficulties and the continuous widening of peak-to-valley difference in metropolitan power grids. This project conducts the in-depth research on the coordinate control method of multi-controllable loads for promoting the renewable energy consumption. This project proposes an elaborate modeling method applicable for the multi-controllable loads such as thermostatically controlled loads (TCLs), electric vehicles (EVs) and high-energy loads (HELs) with the consideration of the response behavior randomness, energy storage characteristics and load distributions, which fully integrates the user-side distributed load resources. Aiming at the renewable energy consumption characteristics and the development trend of the power market in China, this paper proposes a flexible demand response operation mechanism and mode that can balance the interests of multiple parties. Considering the decentralization of controllable loads, as well as user privacy, preferences and free will, this project further proposes hierarchical and distributed interactive control technologies for multiple user types such as smart homes, commercial buildings, electric vehicles and industrial parks. Through the collaborative optimization of intelligent load groups, a multi-objective collaborative optimization scheduling model for load aggregators is established. The research results will provide basic theoretical support for solving the problem of renewable energy consumption and the large-scale development of demand response in China, and make positive contributions to our country's goal of achieving energy conservation and emission reduction, and building an efficient and low-carbon modern energy system.
