Multi-objective transmission network expansion planning in consideration of wind farms

In this paper, a new method for transmission network expansion planning (TNEP) with Multi-objective Memetic Algorithm (MOMA) is proposed. In resent year, the new environment under the power network liberalization and intermittent generation brings about uncertainties in power system operation and planning. It is of main concern to deal with variable output of renewable energy. This paper formulates TNEP with wind farms as a multi-objective optimization problem that optimizes probabilistic reliability index as well as the construction so that a set of the Pareto solutions is obtained through Monte Carlo Simulation (MCS). This paper proposes a new method for TNEP with MOMA that combines Multi-objective meta-heuristics (MOMH) with Tabu Search (TS) to obtain better solution sets. The effectiveness of the proposed method is successfully demonstrated in the IEEE 24-bus system with wind farms.
