Fuel cost minimization with reserve capacity and inter-area flow limit for reliable and cost effective operation of multi microgrids

摘要

Power system is undergoing profound changes such as Distributed Generation, microgrid and then Smart Grid. One of the biggest challenges in it is integration renewable energy sources with conventional DGs for reliable operation of microgrid. An optimization algorithm for reducing total cost considering inter-area power flow limit and reserve capacities is developed and implemented. Power reference points were obtained for each DG with mixed power flow control for cost effective and reliable operation of microgrid. Numerical experiment was performed in MATLAB 2012 using Direct Search Technique.
