    Abstract

    Recently, a multiarea system operation utilized a tie-line has been verified to resolve a shortage of a control capacity of frequency control generators output due to a widespread penetration of renewable energy systems (RES). In order to determine the proper dispatch of the generators output to compensate RES fluctuation in the multiarea system operation, the power system operators should consider power flow constrains and indexes of power system conditions such as the speed of dispatch, the balance of reserved control capacity in each area, and the stability of power supply. In this paper, we propose a methodology to determine multiobjective dispatch candidates of frequency control generators output to compensate RES fluctuation in multiarea system operation considering three indexes, a speed of dispatch, a reserved control capacity, and a transient stability based on optimal power flow and multiobjective particle swarm optimization. The methods determine the dispatch based on Euclidean norm of the indexes in the calculated candidates in order to consider all indexes well-balanced. The effectiveness of the proposed methodology is verified by a numerical simulation used IEEJ EAST 30-Machine Grid Model with much RES, and the effectiveness of the dispatch minimized Euclidean norm is confirmed by comparison to single-objective solution in each index among the calculated candidates.
