Abstract

The invention discloses a microgrid-containing distribution network distributed power supply planning method which comprises the steps of (1) determining that a constraint that microgrid-containing distribution network distributed power supply planning should meet is a microgrid operating domain constraint, (2) determining factors that should be considered in the distributed power supply planningof a microgrid-containing distribution network are economy, environmental protection and reliability, and taking the reliability and environmental protection into economic indicators to carry out weighted summation as a planning target, and (3) solving the model by using a particle swarm algorithm to obtain an optimal planning scheme. According to the distributed power supply planning model with optimal economy, environmental protection and reliability as targets, the influence of grid connection of the distributed power supply on the operating boundary of a microgrid can be effectively reduced, the flexibility and controllability of the micro grid are ensured, the safety of a planning scheme is ensured, the method is suitable for the microgrid-containing distribution network distributed power supply planning, and actual simulation shows the effectiveness and rationality of the proposed method.

Description

technical field [0001] The invention belongs to the technical field of distribution network planning, and in particular relates to a distributed power supply planning method of a distribution network including a micro-grid. Background technique [0002] With the growth of population and the continuous increase of power load demand, the distribution network needs expansion planning to meet future energy demand. Distributed power is mainly combined with wind, light, and storage, and has huge development space and potential. The modern distribution network is gradually developing towards the smart distribution network. In the modern distribution network, there are many types of distributed power sources, various combined operation modes, and a large number of distributed equipment. It is necessary to consider the timing characteristics of various energy sources such as loads, photovoltaics, and wind power. Therefore, it is of great significance to study the optimal allocation ...
