This paper present multi-objective optimization for optimal multi DG location and sizes in radial networks. The objectives fitness considered are minimize active power losses and maximize voltage stability. The hybrid technique based on NSGA-II and Fuzzy logic is used to determine optimal solutions. The proposed technique is tested on diversesizes of IEEE distribution network (10bus, 33bus and 85bus)...
The integration of shunts capacitor in the distribution system can have significant effects on the behavior of the system. An improper insertion of this equipment can cause negative impacts, the solution of these impacts requires an optimal location of shunt capacitors with adequate power injected. The main objective of this study is to determine the optimal placement and size so that the maximum...
Shunt capacitors placement is addressed in this paper. A cost based model to find the optimal size and location of shunt capacitors in a power distribution networks is proposed in which the objective is to minimize the total annual cost function of capacitor placement and power losses. Biogeography-Based Optimization (BBO) algorithm is adopted in this work to minimize the cost function while satisfying...
This paper proposes an improved local search metaheuristic using simulated annealing method with memory component (MSA) for solving the unit commitment problem (UCP) with ramp constraints. The proposed method benefits simultaneously from the advantages of a two metaheuristics: acceptance of “bad” solutions in order to escape from local optimal configurations (SA), and prohibition for a time period...
