Abstract

Disclosed are an active distribution network optimal configuration structure and a configuration method of the active distribution network optimal configuration structure. The active distribution network optimal configuration structure is formed by connecting an active distribution network optimizing system, a fuel oil generator set, a wind power generation set, a photovoltaic power generation set, a storage battery energy storage device, an EV charging pile, an AMI and a load into a distribution network through respective converters, and the active distribution network optimizing system, the fuel oil generator set, the wind power generation set, the photovoltaic power generation set, the storage battery energy storage device, the EV charging pile, the AMI and the load are connected into a large power grid through a public connecting point. Isolated island operation and grid-connected operation of the active distribution network can be achieved by controlling the active distribution network through an active distribution network optimizing system. A dual-layer optimization plane design model suitable for the active distribution network is provided, and comprehensive optimization of distributed power supplies of the active distribution network and scheduling optimization of the distributed power supplies can be achieved.

Description

technical field [0001] The invention relates to the application field of an active distribution network of a power system, in particular to an optimal configuration structure and a configuration method of an active distribution network. Background technique [0002] Active distribution network (ADN) is a system composed of micro-power sources, loads, energy storage systems and control devices. It is a single controllable unit for the large power grid, which can realize the highly reliable supply of multiple energy forms for the load. There are two main characteristics of the active distribution network: one is that it contains local power generation devices, mostly distributed power sources with small capacity. Distributed Generation Resource (DGR) usually refers to mainly using renewable new energy and generating power It is a small modular, environment-compatible independent power supply from a few kW to 50MW, which can meet the specific requirements of the power system a...
