Method for making power generation plan release scheme based on multiple objectives and MPEC planning

Abstract

The invention discloses a method for making a power generation plan release scheme based on multi-objective and MPEC planning. The method comprises steps of 1), setting a unit bid winning multiplier based on the profit maximization of a power grid company and considering the bid winning of a high-cost unit market, and building an upper-layer optimization model; 2) based on the upper-layer optimization model, establishing a lower-layer optimization model by taking the minimum marketization electricity purchasing cost as a target, converting by utilizing a KKT condition, and relaxing a complementary condition by adopting SOS1; 3) converting the upper-layer optimization model and the lower-layer optimization model into a single-layer model for solving by utilizing MPEC planning; and 4) the power grid company formulating a power generation plan release scheme according to the optimization result. According to the method, a power generation plan release scheme and power market clearing arecombined, the release scheme can meet profit maximization of a power grid company and can further consider a market survival problem of a high-cost unit through a double-layer optimization method, anda problem that the scheme is difficult to formulate is effectively solved by utilizing the blocking characteristic of a power network.

Description

technical field [0001] The present invention relates to the technical field of power market and power system, in particular to a method for formulating a power generation plan liberalization scheme based on multi-objective and MPEC (Mathematical Programming with Equilibrium Constraints) planning. Background technique [0002] At present, the way to increase the trading volume of the electricity market is mainly to increase the liberalization of power generation and consumption plans. For power grid companies, the increased degree of liberalization of power generation and consumption plans means that more power generation and consumption plans will become the target of electricity market transactions. Under the condition of a certain amount of total power consumption, this will lead to the power grid obtaining through unified purchase and sale of electricity. Profits are dwindling. At present, the power grid company formulates a detailed power generation plan liberalization ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and proposes a method based on multi-objective and MPEC planning to formulate a power generation plan to break through the traditional scheme formulation method that cannot simultaneously take into account the grid company's own profits and the high-cost unit market To solve the problem of survival, combine the deregulation of power generation plan with the clearing of the electricity market, so that the power grid company can consider the market clearance of high-cost units while achieving the goal of deregulation. Satisfy the grid company's own profit maximization and at the same time take into account the market survival of high-cost units, so as to achieve the various goals of the grid company, further realize the formulation of power generation plans, and alleviate the problem of difficulty in formulating schemes
