Active power security correction in power market

YE Jian~1,WEI Min~2 (1. Dispatching and Communication Center,SMEPC,Shanghai 200025,China; 2. Jiangxi Electric Power Company,Jiangxi 330006,China)  
A method for active power security correction in power market based on genetic algorithm was put forward which means an appropriate regulation of the active power output of the generator to alleviate active power overload of transmission line with the least increase of market purchase cost.The mathematical model for carrying out active power security correction in power market was given and the basic theory and application procedures of genetic algorithm were introduced.The crossover operator and the probability of crossover and mutation of Simple Genetic Algorithm (SGA) were improved appropriately and the Improved Genetic Algorithm (IGA) was formed and its application in active power security correction in power market was expatiated.An active power security correction algorithm was carried out with a 22-node network example and the result showed that the IGA is correct and applicable in engineering practice.
