Description

technical field [0001] The invention relates to a distributed power control system of an energy microgrid based on a wireless sensor network. Background technique [0002] Coordinated control of distributed power sources, energy storage devices and loads in the energy micro-grid to ensure system power balance and power sharing, thereby ensuring the voltage and frequency stability of the energy micro-grid, which is conducive to the efficient use of clean and renewable energy , while improving the stability, reliability and economy of the energy microgrid during operation. However, the traditional energy microgrid centralized control system mainly controls the equipment through the wired communication network. Although it can achieve a certain control effect, when there are many equipment in the energy microgrid and the geographical location is widely distributed, it has the disadvantage of reliability. In addition, when the topological structure of the energy microgrid and c...

However, the traditional energy microgrid centralized control system mainly controls the equipment through the wired communication network. Although it can achieve a certain control effect, when there are many equipment in the energy microgrid and the geographical location is widely distributed, it has the disadvantage of reliability. low reliability, network complexity, high construction cost, and poor scalability, etc., and when the energy microgrid and communication network topology changes, the algorithm needs to be redesigned, and the universality and flexibility need to be strengthened

[0003] The traditional centralized control system conflicts with the nature of the distributed power generation of the energy microgrid. When there are many devices in the energy microgrid and the geographical distribution is wide, the centralized control has the disadvantages of low reliability, complicated network, and construction problems. Problems such as high cost and poor scalability cannot meet the distributed characteristics of energy microgrids
