Multi-Area Dynamic Economic Dispatch by Simulated Annealing

The Multi Area Dynamic Economic Dispatch (MADED) regulate the optimal output in a dynamically changed load demand within a multi area system by considering all the system constraint. Here the basic aim is to schedule the online generators connected in different area in such away that the load demand is to meet along with the minimum operational cost in different operational environment. So, it is a complex optimization which needs to consider different parameters and design the system in an optimized manner under such deregulated environment. In this paper we have applied simulated annealing (SA) method to solve the MADED problem of generating units considering the different operational constraints such as ramp rate limit, transmission losses and tie line constraints. Here we have considered a multi area system with 40 generating units between 4 different areas and the system is optimized using the SA method and results have been described. Based on the result the hourly schedule generation of each area are presented in this paper.
