可中断负荷参与阻塞管理模型与特性分析
|
摘要
确定用户中断损失是可中断负荷参与电力市场运行的难点。提出基于投入产出的中断损失评价方法,指出每单位负荷的价值是不同的,中断损失应根据电力边际价值评价,并通过两种电力需求曲线量化分析。Pool模式下,以阻塞成本最小为目标,构建协调机组出力调整与可中断负荷调度的直流最优潮流模型,该模型为一个二次规划问题,求解方便,降低了阻塞管理的复杂性。最后,IEEE-14节点算例验证模型有效性,并给出可中断负荷参与电力市场运行几点建议。
How to identify the customer's loss from interruptible load(IL)is a key issue for IL to take part in the electricity market. The paper evaluates the loss of IL based on an input-output analysis method,and points out that their economic values are different for various types of loads,thus the loss should be evaluated based on the marginal value of electricity. This paper also quantifies the loss through two types of electricity demand curves. Under the pool mode in electricity market,a DC optimal power flow model is established to coordinate the unit output adjustments and the dispatch of ILs with the objective function of minimizing the congestion costs. The problem is quadratic programming problem,which is easy to solve and reduces congestion management's complexity. Finally,the IEEE14-bus system is used to demonstrate the feasibility of the model. Several suggestions are given on the participation of IL in power mar-kets.
