摘要

提出了主动配电网扩展规划的混合整数二阶锥规划模型

该模型以总的投资与运行费用最小为目标函数。文中考虑了4种主动管理措施降低规划方案成本及未来的运行风险

包括有载调压变压器调节、切机、切负荷及无功补偿。规划措施包括主动管理、新建线路、新建变电站、扩建变电站、新建分布式电源。配电网规划是一个混合整数非线性规划问题

再加对各种主动管理措施及未来不确定性的考虑

配电网规划问题求解变得相当复杂。基于配电网潮流方程及约束松弛技术

建立了配电网规划的二阶锥规划模型

并利用改进的IEEE 33节点系统及Miranda 54节点系统进行了算例验证。

Abstract

A mixed integer second-order cone programming(SOCP)model for active distribution network(ADN)expansion planning is proposed

which minimizes the total investment and operation cost. Four active management strategies consisting of on load tape changer(OLTC)tap adjustment

distributed generator(DG)curtailment

load curtailment

and reactive power compensation are considered to cut the planning cost and future operation risks of the planning. The planning model allows alternatives to be considered for active management

new wiring

new substation

substation expansion and DG installation. The distribution network planning(DNP)problem is a mixed integer nonlinear programming problem. What with the active management and uncertainties

the DG integration has made the DNP problem considerably complicated. In order to find a polynomial time computable model

the DNP problem is converted to a SOCP model through power flow equations and constraint relaxation. A modified IEEE 33-bus system and Miranda 54-bus system are used to testify the proposed model. This work is supported by National High Technology Research and Development Program of China(863 Program)(No. 2014AA051901)and State Grid Corporation of China(No. 52094015000A).
