| Abstract: in this Paper, Optimal placement and sizing of DGs is considered as an engineering optimization problem. Due to integration and influence of DGs in distributed networks, optimal location and sizing of them are done based on objective functions such as: voltage profile improvement, power loss reduction, reliability improvement, restraining the increase of power plant, etc. These goals considering the NSGA-II algorithm with cold standby strategy will be investigated and simulated on IEEE 33-bus standard test system. In order to implement the concept of Cold Standby theory, a group of DGs are considered which are off in normal condition but in fault condition, these DGs turn on and help to reconstruction the network. In order to measuring reliability, used the expected energy not supply (EENS) index. Optimization is done with two goals: reduction of EENS and the cost, including investment cost and power loss cost. Moreover, voltage profile improvement has been applied as a function penalty. Simulation has been done in MATLAB software and results show the effectiveness and capability of proposed algorithm. |
