Optimization of distribution network incorporating distributed generators: An integrated approach

Abstract:

Previous studies of distributed power and network focused only on the optimization of either the microgrid load dispatch or reconfiguration power loss. Micorgrid economic load dispatch approach normally does not support distribution network. Network reconfiguration usually does not take distributed generators into consideration. Thus, it is necessary to integrate these two sub-problems together in order to benefit the whole network. In this paper, an integrated solution that takes care of both microgrid load dispatch and network reconfiguration is proposed. The stochastic nature of wind, PV and load is taken into consideration. The forecasting of the wind, PV and load data are considered. The four bio-inspired optimization schemes are adopted to solve the problem. The results obtained have shown that the four optimization techniques are all capable of solving this problem. By using the integrated approach, microgrid can be incorporated into the network more effectively. The network can adjust itself more efficiently to allow utilization of the renewable energy resources. © 1969-2012 IEEE.
