Research on multiple collaborative management and control system of power grid based on"zone I +"
Combined with the"double carbon"strategic goal,this paper analyzes the"double high"characteristics of the power system,and combs and considers the overall architecture of the existing dispatching automation technology support system.It puts forward the working idea of building a multi-element collaborative control system based on"zone I +",expand the boundary of the control object through 5G wireless communication acquisition technology,as a supplement to the wired acquisition of zone I dispatching automation system,and realize the large-scale access,monitoring and control of multiple types of adjustable resources such as distributed power,local power plants,electric vehicles,intelligent buildings,etc.By carrying out pilot work,exploring a variety of technical routes and forming a unified research scheme for promotion,the data of 14 10 kV distributed photovoltaic,9 local power plants,36 000 low-voltage distributed photovoltaic power generation units have been observed and measured,and the smooth adjustment and control of 6 10 kV distributed photovoltaic units,as well as the adjustable and controllable data of 65 low-voltage distributed photovoltaic power generation units have been achieved.Through online perception,intelligent decision-making and interactive response to various resources of the new power system,we will promote the transformation from the existing"source follows the load"to the"source network load storage coordination and interaction"regulation mode,promote the consumption of new energy,assist the power grid in peak shaving and valley filling,and improve the safe,efficient,clean and low-carbon economic operation level of the power grid.
