Abstract
Renewable energy sources are omnipresent freely available, ecological friendly and they are considered as promising power generating sources due to availability and topological benefits for local power generations. Wind and solar energy have become very essential and important in the generation mix as a result of rising energy demand and environmental issues. Solar energy system might be compensate the wind intermittency generation resource due to lesser start up time, lower operating cost and good ramping capabilities. The generation scheduling for wind-solar energy with thermal unit system in deregulated environment, minimize the total thermal fuel cost and maximize the profit of generation companies, subject to many constraints. While performing the generation scheduling problem by Lagrangian relaxation based particle swarm optimization method the hourly load, wind velocity and solar radiation must be forecasted to prevent the errors. The generation scheduling formulations are involved the perspective of a generation company (GENCO). The deregulation environment is one where the generation, transmission and distribution do not depend on each other. To demonstrate the uncertainty in the proposed method the generation scheduling problem is performed in a simplified generation system.
