计及能效电厂优化配置的输电系统两层规划

摘要

提出能效电厂优化配置原则.以两层规划理论为基础建立计及能效电厂优化配置的输电系统两层规划模型,上层模型以输电系统投资和能效电厂投资的总成本最小为目标,下层模型以能效电厂投资成本最小为目标,上下层之间存在交互作用,最终由上层决策获得输电系统规划方案.采用遗传算法和原对偶内点法相结合的混合算法对所建的输电系统规划模型进行求解.18节点和46节点系统算例结果证明了所提模型和算法的可行性与有效性.%The principle of optimal EPP(Efficiency Power Plant) placement is proposed and with the consideration of the optimal EPP placement,a two-level planning model based on two-level planning theory is developed for transmission system,of which,the upper model takes the minimum total cost of transmission system and EPP investment as its objective while the lower model takes the minimum cost of EPP investment as its objective.With the interaction between two levels,the transmission system planning scheme is finally determined by the upper model.A hybrid algorithm combining genetic algorithm and primal-dual interior method is adopted to solve the proposed planning model.Results of case study for 18-bus and 46-bus systems verify the feasibility and efficiency of the proposed model and algorithm.
