Abstract

The invention discloses a power grid load margin calculation system. A regional power grid is divided into a plurality of independently controlled power grid partitions according to a preset rule, andeach regional power grid partition is configured with a power grid partition control module; partition power utilization acquisition modules are configured on the power grid partition control modulesrespectively, the partition power utilization acquisition modules are used for acquiring power utilization information of the corresponding power grid partitions in real time, and the power grid partition control modules calculate partition load allowance of the power grid partitions according to the power utilization information; a power grid master control module is used for receiving data of the power grid partition control module and sending a control instruction to the power grid partition control module; and a power grid master control module counts the partition load allowance of all the power grid partitions and obtains the real-time power grid total load allowance. According to the invention, the regional power grid is partitioned, and the electrical load of each power grid partition is independently obtained, so that the electrical load of the whole power grid is calculated in an integrated manner, and the load margin of the power grid is obtained.

Description

technical field [0001] The invention relates to the technical field of grid load margin monitoring and application, in particular to a grid load margin calculation system and method and a charging pile access power distribution method. Background technique [0002] The development of new energy vehicles represented by electric vehicles is a very clear industry development direction in the current society. New energy vehicles use unconventional vehicle fuels as power sources, such as on-board batteries. These new energy vehicles are equipped with charging piles. But the installation of charging piles in the regional grid is the most important problem to be solved. [0003] At this stage, the distribution network for new energy vehicles has not yet been established in residential areas, communities, parking lots and other places with a lot of parking. Adding charging piles on the basis of the existing distribution network will easily increase or even exceed the distribution ne...
