Abstract

The invention discloses a power distribution network voltage regulation method based on an internet cloud platform and distributed energy storage. The distributed energy storage accesses to the cloudplatform through the internet, and sends an energy storage state and other data to the cloud platform; the cloud platform monitors power distribution network flow in real time, when a voltage peak ofa node in the power distribution network deviates from the normal range, the internet platform performs optimal computation on the power flow through a voltage sorting search method, determines the optimal distributed energy storage charging / discharging policy, and then sends the charging / discharging instruction to the distributed energy storage unit. The voltage is regulated to the normal range by using the charging / discharging of the distributed energy storage, and the safe and stable running of the power distribution network is maintained.

Description

technical field [0001] The invention relates to the technical field of distribution network voltage regulation, in particular to a distribution network voltage regulation method based on an Internet cloud platform and distributed energy storage. Background technique [0002] In recent years, due to the energy crisis, environmental deterioration and many large-scale power outages, distributed power has attracted more and more attention for its unique environmental protection and economy. Large-scale use of renewable energy has become a major trend in the world's energy development. Compared with traditional power plants, distributed power supply has unique advantages. Distributed power supply uses renewable energy as power generation material. These clean energy sources can greatly reduce the emission of harmful gases such as carbon monoxide and nitrogen monoxide, and can also reduce carbon dioxide. and other greenhouse gas emissions, thereby protecting the ecological enviro...
