Optimal Wind Power Planning Considering Power System Adaptability and Economy

Abstract

Wind power planning towards large-scale accommodation of wind power while satisfying technical and economical constraints, it should consider power system adaptability and economy when giving full play to the wind benefits. This paper considers the relationship among wind power accommodation, construction of transmission lines and conventional unit operation costs and proposes an economic and reasonable wind power planning approach aiming at accommodating wind power efficiently and effectively. Combined the constrains of peak load regulation and network construction together, optimal wind power planning model is established, and based on the system operation simulation, a series of wind power planning evaluation index are obtained, which can estimate the wind power planning scheme from multiple angles. Finally, the feasibility and reasonability of the proposed planning approach has been verified by a numerical test system.
