Based on theanalysis on energy-supply features, power demand and the technical and economic performances of various powersources in Guangdong, the power sources construction scale and its structure are studied and analyzed in detail byusing Generation Expansion Software Package (GESP). The future development of Guangdong electric power sourcesunder the new situation of "Power from West to East" is studied as well.[展开更多

The five formulations of optimal demand are developed to solve optimal contract capacity for TOU (time of use) customer. Results indicated that, the CSO algorithm is highly helpful to Taiwan Residents industries on the optimal demand decision. Also the CSO is superior to PSO (particle swarm optimization) in the fast convergence and better performance to find the global best solution in the same iterations.展开更多
