蓄電池による負荷周波数制御の一考察

Abstract

The electric power supply，with which the electric power system is the stability and the high reliability，is required more and more by upgrading and diversification of social life and industry. In power system，the participation of In-dependent Power Producer (IPP)，D istributed Generator (DG) such as wind power generation，so lar photovoltaic generation，etc. seem to increase with deregulation and liberalization of power market recently. And，electricity trading which is the region monopoly until now，becomes also possible such as electricity trading and electric power consignment which exceeded the region. Therefore，so phisticated control technology is more required. And，the control method of electric power in the large-scale electric power system is complicated. In this paper，th e case by DG with the storage equipment in which system frequency control was carried out was examined. It is an item on carried out examination item. 1) The case in which the proportional control using frequency variation was carried out. 2) The case in which output setting control using the load estImation method and the proportional control using frequency variation was carried out. The effectiveness of these techniques was examined using small generator，in verter and storage battery. .
