Considering of the User Side Energy Storage Planning of Two-Part Prize System

Abstract

随着储能技术的不断发展，储能在电网中的应用场景不断增多。在两部制电价下，储能应用在电力用户侧，不仅可以为用户带来套利收益，而且可以减少用户的基本电价。本文提出一种在两部制电价和储能周循环特性下，以用户侧储能的容量、运行方式为决策变量，以用户在储能全寿命周期下的净收益为目标函数，构建了配电网用户侧储能混合整数线性规划配置模型(MILP)。最后以深圳某用户为例，验证了所提方法的可行性和有效性。本方法是针对两部制电价下电力用户的储能优化配置，使用户充分运用储能获得最大收益，从而使储能价值得到充分发挥。 With the development of energy storage technology, the application scenarios of energy storage in power grid are increasing. Under the two-part electricity price system, the application of energy storage on the power user side can not only bring profit arbitrage for the user, but also reduce the user’s basic electricity price. In this paper, a mixed integer linear programming configuration model (MILP) of energy storage on the user side of the distribution network is proposed under the two-part price system and the week cycle characteristics of energy storage. The capacity and operation mode of energy storage on the user side are taken as the decision variables, and the net income of the user under the life cycle of energy storage is taken as the objective function. Finally, a user in Shenzhen is taken as an example to verify the feasibility and effectiveness of the proposed method. This method is aimed at the optimal configuration of energy storage for power users under the two-part system, so that users can make full use of energy storage to obtain the maximum benefits, so as to give full play to the value of energy storage.
