Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent dispatching of electric power systems, and in particular relates to a distribution network energy management system based on data collection and analysis. Background Art

[0002] At present, in order to improve the utilization rate of energy or energy, energy management systems have received more and more attention. In terms of structure, energy management systems have various ways of managing energy. One of the energy management methods is to use the intelligent management mode of the energy management system to reasonably dispatch different forms of energy (energy generated by distributed power generation) to improve the utilization rate of the dispatched energy. In this way, different forms of energy can be reasonably dispatched to provide users with the required energy.

[0003] However, most of the current energy management methods are established for single energy (energy generated by a single power generation) networks, which leads to low energy dispatching efficiency, because single energy cannot be dispatched and is directly used. For different forms of energy dispatching, energy management methods are proposed for different forms of energy dispatching in distribution networks, but different forms of energy dispatching in distribution networks all use the concept of energy distribution to dispatch different forms of energy. This method concentrates different forms of energy and distributes the concentrated energy in an average distribution manner. There is a lack of independent distribution of different forms of energy after concentration, and the actual operation and dispatching effect of the distribution network cannot be guaranteed. Therefore, it is necessary to improve the different forms of energy dispatching methods in the distribution network to ensure the actual operation and dispatching effect of the distribution network.
