Problems solved by technology

The whole process is essentially a heuristic method based on priority. Not only is the workload heavy, but the scheme is not refined and optimized enough, so the peak shaving capacity is insufficient, and the peak shaving pressure in areas with large peak shaving gaps cannot be effectively relieved.

Abstract

The present invention discloses a method and a device for making a plan of power transmission and receiving between regions. The device comprises the steps of: determining a peak regulation demand factor [Alpha]I of the power grid of each region according to the peak regulation demand of the power grid of each region; constructing a target function as shown in the description of an optimization model of a plan of power transmission and receiving according to the peak regulation demand factor [Alpha]I of the power grid of each region; establishing constraint conditions of the target function; and establishing the optimization model of the plan of power transmission and receiving between the regions according to the target function and the constraint conditions; performing optimization calculation of the optimization model to obtain a plan of power transmission and receiving between the regions. The method and the device introduce the peak regulation demand factor to allow the optimization model to consider the actual peak modulation demand of the power grid of each region and consider the complementary features of the load and the power supply between the regions so as to effectively relieve the peak modulation pressure of the power grid of each region, improve the peak modulation capacity of the power grid of each region and the economic benefit of operation of the power grid and have high feasibility and reliability, and therefore, the method and the device for making a plan of power transmission and receiving between regions are suitable for engineering reality and the management system of large-region power grids in our country.

Description

technical field [0001] The invention relates to the field of power grid economic operation, in particular to a method and device for formulating an inter-regional power transmission and reception plan. Background technique [0002] In the power system, the interconnection of regional grids brings great benefits to safe and economical operation. The multi-region interconnected power system can not only allocate power generation and power supply more reasonably, shift peaks and valleys, reduce the peak load of the joint system, but also make more reasonable use of various power resources such as water, fire, and wind, so as to achieve better overall efficiency. benefit. Formulating and coordinating power transmission and reception plans in various regions can make full use of the resources of the entire network, and it is also an effective way to alleviate the pressure of peak regulation on the power system. [0003] At present, in the actual situation of my country's large ...
