OPTIMAL DG ALLOCATION IN DISTRIBUTION NETWORK USING STRENGTH PARETO MULTI-OBJECTIVE OPTIMIZATION APPROACH

Nowadays, DGs are widely used in the power systems to improve the overall conditions of the network. Less environmental impact, high electric efficiency, low variable maintenance cost, quick start up, low installation cost and many other benefits, encourage the system manager to utilize this type of generation in the network. One of the most important issues about DG is allocation size and place of DG in the network to achieve optimal using of it. Strength Pareto as a multi-objective algorithm optimizes DG size and place while DG cost and system total power loss are optimization objectives. This program gives several results which all of them are optimal and designer could select one of them according to his interest. This result is known as Pareto front. Pareto front is compared with result of GA and its capability is shown.
