The randomness and anti-peak shaving characteristics of wind and solar output make it more difficult for the power grid to absorb renewable generation. Using the flexible and adjustable characteristics of the source side and the load side, the bilateral participation rules of source and load are designed to guide the source and load to carry out bidirectional power coordination across time to support the efficient consumption of renewable energy. First, the basic rules and principles of bilateral participation of the source-load are sorted out, transaction subjects, varieties and models are clarified, and their participation rules are designed. Secondly, according to the bilateral participation rules of source and load, a joint optimal dispatch model of day-ahead energy and reserve is constructed taking into account the bilateral participation of source-load, so as to help the consumption of renewable energy and reduce the electricity cost of industrial users. Thirdly, to solve the problem of multi-scenario mixed integer programming, an improved progressive hedging decomposition algorithm is used to solve the problem, and the convergence of the model is ensured through the heuristic variable "fix-screen-relax". Finally, an example analysis is carried out on the basis of the IEEE 118-node system, which verifies the effectiveness of the proposed joint clearing model of energy and reserve in promoting energy consumption.
