摘要

发展主动配电网是消纳间歇性分布式能源的有效途径。文中研究主动配电网的优化运行控制技术，提出了全网集中优化、区域协调校正的控制方法。在长周期内协调全网有功和无功资源，基于半定规划理论建立了以网损最小为目标的最优潮流模型，实施全网优化控制。在短周期内，将电网划分为若干个可控区域，提出了区域内分布式电源、电压无功设备、柔性负荷的协调校正控制策略，跟踪全网优化控制给出的区域运行目标。仿真算例表明，全网优化控制能有效降低网损，区域校正控制能准确跟踪全网优化目标，将电网始终维持在最优运行状态。

Abstract

The development of active distribution network (ADN) is an effective approach to the consumption of intermittent distributed generation. Based on control technology of ADN optimal operation

a control method of global centralized optimization and regional coordinated correction is proposed. In the long cycle

global optimization control is implemented and an optimal flow model based on semi-definite programming theory is developed to get minimum power loss by coordinated globally active and reactive power resources. In the short cycle

the network is divided into several controllable regions

and the coordinated correction control strategy for distributed generation

voltage reactive power equipment

and flexible load for tracking the regional optimal operation objective is proposed. The simulation example demonstrates that global optimization control is able to effectively reduce power loss while regional correction control will accurately track the global optimization objective

maintaining the network optimal state of operation from beginning to end. This work is supported by National High Technology Research and Development Program of China (863 Program) (No. 2014AA051901).
