Distribution network intermittent energy consumption system and method based on active mechanism

Abstract

The invention discloses a distribution network intermittent energy consumption system and method based on an active mechanism. The method comprises the following steps of: locally consuming intermittent energy at an intermittent energy access point by using a source network coordination controller; if the intermittent energy is excessive, transmitting the excessive energy to a medium-voltage network distribution layer; and realizing intermittent energy consumption through global optimal coordination and a distribution self-government active mechanism algorithm by using an active network distribution controller in the middle-voltage network distribution layer to realize optimal scheduling, running way optimization and voltage coordination control of a power distribution network. Due to the adoption of the system and the method, maximum consumption and efficient utilization of intermittent energy accessing to the power distribution network are realized on the premise of meeting safe and economic running of the power distribution network.

Description

technical field [0001] The invention relates to the intermittent energy consumption technology in the field of smart grids. The invention proposes an active mechanism-based intermittent energy consumption system and method for a power distribution network. Background technique [0002] Distributed power generation (especially renewable energy) has become an important means for the power industry to cope with energy crisis and environmental protection due to its high efficiency, flexibility and sustainability. The access of distributed power generation can relieve the pressure of load growth and delay the upgrade of power grid And reduce the energy loss of grid operation. However, distributed renewable energy, such as wind energy, solar energy, etc., is greatly affected by the environment, and its intermittency and volatility will bring a series of problems to its access to the grid: including power flow, voltage fluctuations, short-circuit capacity, power quality and stabil...

AI Technical Summary

Problems solved by technology

However, distributed renewable energy, such as wind energy and solar energy, is greatly affected by the environment, and its intermittency and volatility will bring a series of problems to its access to the grid: including power flow, voltage fluctuations, short-circuit capacity, power quality and Stability etc.

Its centralized management and control of distributed energy is an effective means to solve the access of distributed power generation at present. However, due to the small scale of the micro-grid, the access of intermittent energy is also relatively concentrated, so the micro-grid cannot achieve intermittent energy access. Large-scale and large-capacity consumption of energy
