Research On Energy-saving Generation Dispatch Model And Operation System For Power Grid Enterprises

The implementation of energy-saving generation dispatch is a wide-related and complicated engineering. It is the major reformation of the existing generation dispatch system of the power market. The challenges of safety and economic operation are presented. How to realize the environmental and economic scheduling based on the security and stability of the power system and how to promote its effective implementation are to be solved urgently.Firstly, based on its basic principles, the comparation between it and the economic dispatch is given from the effectiveness and efficiency, and the analysis of the its impact on power grid enterprises is given. Taken Guangxi and Sichuan and other province as an example, its successful experience is given.Then, the power-saving factor is expressed as the energy consumption of thermal power units, and the environmental factor as the increased cost of the coal consumption rate and emissions, and the economic benefits factor as the cost of electricity purchase. The nominal cost of the electricity purchase is built, and the multi-objective optimization model is built with the constraints of the power system, taken the minimization of the mathematical expectation of the cost as the objective function and solved by the PSO algorithm.Finally, its operation system is built on the basis of its organization and core processes. And the operating mechanism and technical support system and risk prevention mechanism are contained. Construction of administration should be standardized and specialized and concise and orderly and highly synergistic. The core business processes mainly consist of implementation of its plan and information dissemination. The operating mechanism is built from the demand-side and renewable energy operation management. Its technical support system is built to improve its efficiency. And the preventive measures of various types of risks are given after grid dimension of risk is made.There are designed to promote its smooth transition, and to provide a comprehensive management strategy on the realization of its refined management for the power grid enterprises in China.
