Optimal Scheduling of a Regional Power System Aiming at Accommodating Clean Energy

The regional power system is an essential mechanism to solve the unbalanced distribution of resources and achieve more efficient resource allocation. In this paper, optimal scheduling model developed, maximize social welfare minimize clean energy electricity curtailment. This can realize allocation generation maximum accommodation multiple types energy, by minimizing sum purchase cost dynamic penalty energy. Meanwhile, it considers modeling key AC/DC hybrid tie-line in grid. To end, methods transmitted tie-line, net loss stair-like operation DC power, constraints are proposed. Then a simulation example study conducted verify effectiveness model, which proves that stimulate optimization potential better than provincial system.
