Source network load storage cooperative interaction electric power spot market clearing method

Abstract

The invention belongs to the technical field of electric power market transaction, and discloses a source network load storage cooperative interaction electric power spot market clearing method, whichcomprises the steps of submitting operation parameters and bidding information by a market main body to an electric power scheduling mechanism and a transaction center in a market transaction declaration process; determining boundary conditions cleared by the market according to information such as predicted generated output, load prediction, network electrical parameters and a power system topological structure by a power scheduling mechanism according to uncontrollable new energy such as wind, light and radial-flow hydropower; constructing a constraint mathematical model of the source network load storage square in the power market joint clearing optimization model; constructing a power market joint clearing optimization model of source network load storage cooperation; and solving andpublishing the bid winning capacity and the real-time electricity price of each market subject. According to the method, the adjustment main body is extended to the source network load storage squaremarket main body, so that efficient configuration and complementary optimization of flexible adjustment resources of the power system in the market environment are realized, and the market efficiencyand the robustness of the power system are improved.

Description

technical field [0001] The invention relates to the field of electric power market transactions, in particular to a method for clearing an electric power spot market in which sources, networks, loads and storages cooperate and interact. Background technique [0002] The intermittence, randomness, volatility and uncontrollability of new energy power generation will affect the safe and stable operation of the power grid. The rising penetration rate of new energy power generation poses higher challenges to the stable and reliable operation and efficient dispatching of the power system. The power system must have sufficient flexibility to cope with the impact of a high proportion of new energy generation connected to the grid. [0003] In the electricity market environment, market entities complete information interaction with power dispatching agencies and trading centers through centralized bidding platforms or contract markets. Under the current power spot market model, pow...
