Abstract

The present invention provides a power supply configuration planning method and its system. The distributed power supply configuration planning method takes into account the impact of distributed power supply access on voltage sag, studies the fault characteristics of distributed power supplies under fault conditions, and builds a The mathematical model of the inverter-type distributed power supply when voltage sag occurs; considering the power quality requirements of sensitive users, STATCOM and other equipment are installed within the scope of the distribution network to meet the differentiated needs of different sensitive users for power quality; In order to ensure the economy of the planning scheme and the satisfaction of users, comprehensively consider the investment and construction costs and operation and maintenance costs of distributed power sources, STATCOM construction and operation and maintenance costs, user satisfaction and other factors, and rationally configure distributed power sources to obtain the best results. Excellent planning scheme.

Description

technical field [0001] The invention belongs to the field of distributed power supply configuration planning, and in particular relates to a power supply configuration planning method and system thereof, in particular to a distributed power supply configuration planning method and system thereof taking into account user satisfaction. Background technique [0002] Due to the inherent decentralization and randomness of output, distributed power is generally connected to the distribution network for operation. At present, the access capacity is relatively small, and the impact on the distribution network is limited, but in the future, with the maturity of distributed power generation technology, the cost of distributed power generation will decrease day by day, and the penetration rate of distributed power generation in the distribution network will continue to increase. It will affect the node voltage, line flow, short-circuit current, reliability, etc. of the distribution net...
