Optimal Robust Microgrid Expansion Planning Considering Intermittent Power Generation and Contingency Uncertainties

This chapter presents an approach for robust microgrid expansion planning (RMEP) considering intermittent power generations (IPGs) and responsive loads (RLs). A framework for RMEP is presented based on stochastic-robust optimization for the optimal presence of active microgrid in the electricity market taking into account the IPGs/RLs and contingency uncertainties. The microgrid topology and power flow constraints are considered. The formulated problem is modelled as a mixed-integer nonlinear programming (MINLP) problem, and a heuristic optimization method is utilized. This model is applied to the 9-bus and 33-bus test systems, and the numerical results assess the effectiveness of the introduced method.
