Abstract

The invention relates to a real-time power network thermal power plant economic operation evaluation optimization algorithm. The algorithm includes the following steps that: problems in power plant generator combination are solved through efficiency prioritization; problems in target function primarization are solved through utilizing linear programming; and problems of security constraints of network operation and influence of fault switching-on and switching-off on a network structure are solved through utilizing the advantages of direct current load flow. According to the real-time power network thermal power plant economic operation evaluation optimization algorithm of the invention, a loop iteration method in which efficiency prioritization, linear programming and optimal load flow are combined together is adopted, so that economic operation evaluation of a thermal power plant in a power network can be performed fast, and computational analysis services can be provided for on-line evaluation.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a real-time power grid economic operation evaluation fire electronic optimization algorithm. Background technique [0002] So far, there have been a lot of research work at home and abroad on how to formulate daily power generation plans for thermal power plants based on grid security, economy, and unit characteristics. The research on optimization algorithms is still mainly based on classical optimization algorithms, such as linear Programming method, quadratic programming method, nonlinear programming method and dynamic programming method, etc., are also based on modern artificial intelligence, such as genetic algorithm, artificial neural network method, ant colony algorithm, chaos optimization method and evolutionary algorithm. Using these single and simple algorithms will encounter problems such as limited accuracy of calculation results, combination explosion, and no solution. ...
