Abstract

The invention discloses a demand side management system of a high-permeability intermittent new energy access distribution network. The distribution network includes intermittent new energy and load groups. The demand side management system adopts a hierarchical control architecture, and includes an upper demand side decision system and a lower load group control system. By adopting the hierarchical control architecture, dividing loads into a plurality of load groups and setting the decision system and the group control system, the communication network is simplified, and the system scalability is enhanced. On one hand, the computational complexity of the upper decision system is simplified, and the response speed is increased. On the other hand, the lower group control system can be closely linked with specific load equipment, can analyze the load characteristics and carry out generalized battery equivalence, and does not damage the use characteristics of loads while controlling loads.

Description

technical field [0001] The invention relates to the technical field of intelligent distribution network, in particular to a demand-side management system and method for high-permeability intermittent new energy access to distribution network. Background technique [0002] With the vigorous development of new energy technologies, large-scale renewable energy is connected to the grid, and these renewable energy are often intermittent, typically photovoltaic and wind power. The intermittency of new energy sources brings new challenges to power grid dispatching, such as power reverse, voltage over-limit, and large power fluctuations. With the rise of the smart grid and the development of communication technology, the information channel between the demand side and the grid side increases rapidly, and it becomes feasible to realize the on-site consumption of intermittent energy through demand-side management, and the demand-side management technology can effectively improve Dist...
