Abstract

The invention is applicable to the technical field of power network dispatching, and provides an UHV receiving-end power network peak load regulation control method, comprising the following steps: obtaining the UHV receiving-end power network in-network unified load regulation; If the load in the network is in the output range of the adjustable unit, the output level of the adjustable unit in thenetwork will be adjusted. If the load in the network is not in the output range of the adjustable unit, the power of the storage power station will be regulated. If the power of the storage power station can not meet the peak load regulation condition of the first power network, the transmission power of the UHV transmission channel is regulated. If the transmission variation of the UHV transmission channel can not meet the peak load regulation condition of the second power network, the charging and discharging power of the energy storage device is regulated. If the charging and discharging power of the energy storage device cannot meet the peak load regulation condition of the third power network, the load power of the terminal on the user side is adjusted so that the load power of the terminal on the user side meets the peak load regulation condition of the fourth power network. The invention can realize the peak clipping and valley filling of the power network, and ensure the safeand stable operation of the power network and the reliable power supply.

Description

technical field [0001] The invention belongs to the technical field of power grid dispatching, and in particular relates to a peak-shaving control method for an UHV receiving-end power grid. Background technique [0002] With the rapid development of UHV power grid and new energy power generation, the UHV receiving end power grid is facing the dual pressure of simultaneously consuming distant clean power and fully consuming local new energy power. In the northern region, winter is faced with the multiple constraints of a high proportion of thermal power heating units, limited peak shaving depth, and serious shortage of peak shaving power sources such as hydropower and natural gas power generation. In addition, under the situation of air pollution prevention and control, the use of heat to determine power is even more serious. Limit the means of power grid peak regulation. Especially during the winter holidays, the industrial production load is significantly reduced, the bas...
