[0049] figure 1 It is an overall configuration diagram of the power system stabilization system according to the first embodiment of the present invention. figure 1 The power system stabilization system 10 shown is a system for stabilizing the power quality of a power system 124, wherein the power system 124 will be converted from large-scale power supply equipment 123 based on thermal power stations and nuclear power stations. The power provided by the solar power generation equipment 121 and the wind power generation equipment 122 is distributed to the charging station 107 and the user 108 via the power distribution substation 125 and the transmission line 126 . Here, in the charging station 107, in addition to the existing dedicated equipment such as gasoline stations, it also includes simple equipment installed in parking lots of commercial facilities and metered toll parking lots. Large users such as commercial and industrial facilities and general households.

Abstract

PROBLEM TO BE SOLVED: To accurately control power to charge each electric vehicle at each charging station by guiding a right number of electric vehicles at the right time to the charging stations to balance between supply and demand in a power system.SOLUTION: In order to allow a right number of electric vehicles to consume power by sharing total charging power allocated to a group of charging stations in each power distribution area planned by a power system monitoring control system, a charge monitoring control center invites travelling electric vehicles to apply for charging at charging stations, selects a right number of electric vehicles among the electric vehicles which have applied for, and determines an amount of charge for each electric vehicle by distributing the total charging power to the selected right number of electric vehicles. The charge monitoring control center also individually controls charging power of electric vehicles at respective charging stations by individually guiding electric vehicles to respective charging stations.

Description

technical field [0001] The present invention relates to a technique for stabilizing power quality of an electric power system by controlling the amount of charge given to an electric vehicle. Background technique [0002] In recent years, the demand for energy saving and cost saving has greatly increased. In November 2007, in the Energy Conservation Sector Policy Subcommittee of the General Resources and Energy Research Council, an advisory body for the Ministry of Economy and Industry, we learned about the revision of the Energy Conservation Law (Revision of the Energy Conservation Law), which was considered for the achievement of the greenhouse gas reduction target for the Kyoto Protocol. Report, on December 12 of the same year, the department also understood and sorted out the final report. [0003] According to this report, energy conservation is one of the most important issues as the basis of national life and economic activities for our country, which relies on overs...
