Multi-energy flexible control system and method for urban and rural residents based on demand side response

Abstract

The invention discloses a multi-energy flexible control system and method for urban and rural residents based on demand side response. During application, after receiving the control command issued by the grid end through the special electrical network, the primary station of demand side response performs the full-view positioning for load shedding of power grid in the whole district and control path setting according to the electricity information of residents and load priority of users, and quickly and precisely locates the scope of residents joining the load control, control degree of adjustable load and control time of alternative operation of controllable load. On a basis of guaranteeing the normal operation of load closely related to the lives of residents, the whole cross-regional automatic demand side response flexible regulation control is realized through remotely adjusting the parameters of adjustable temperature load, etc. and controlling the operation time of controllable load. Meanwhile, the energy node characteristics and coordination relationship of residential electricity equipment, distributed power source and stored energy are comprehensively considered to dynamically adjust the input and output amount of network source, distributed power source and stored energy, so as to match the demand side response requirements and electricity requirements, and improve the use ratio of distributed power source to the greatest extent from the view of supply side.

Description

technical field [0001] The invention relates to the technical field of intelligent power consumption and power dispatching, in particular to a multi-energy flexible control system and method for urban and rural residents based on demand side response. Background technique [0002] In the 21st century, with the advancement of science and technology and the development of the economy, the global demand for electric energy is also increasing year by year, and the power gap is gradually increasing. The peak-to-valley difference in power load has further increased, and the growth of energy demand in various places has far exceeded the growth of power production capacity. The contradiction between supply and demand has deepened day by day. Insufficient power grid capacity and environmental pollution. These problems lead to frequent power restrictions and blackouts at times of peak power demand. Traditional coping methods such as power cuts in some areas during peak hours and sta...
