An Inclusive Review on Load Frequency Control in Deregulated Market
International Journal on Electrical Engineering and Informatics
Load frequency control is one of the most important ancillary services brought in after deregulation of electricity market, which must be procured by the system operator from the market participants by some regulatory mechanism or by using market-based approaches. This paper presents an overview of load frequency control service prevailing in India and other developed countries after deregulation. Brief review on various control strategies proposed by researchers to design LFC controller to
... C controller to regulate the frequency in deregulated market has been covered. Finally, price based frequency linked load frequency control scheme has been discussed. 595 implemented successfully. Section III discusses the frequency control service adopted in India with its operational procedure. Section IV, analyzes about a variety of load frequency control mechanisms after electricity deregulation. Frequency linked real time pricing scheme proposed for deregulated electricity market is discussed in Section V. Finally section VI presents the conclusions of the study. Frequency Control Service: International Context This section covers short-lived history of the frequency control service adopted in country like Australia, Spain, California, New York, Argentina U.K. and Nordic Countries. A. New York, USA In the New York control area, New York ISO (NYISO) offers frequency response ancillary services by committing on-line generators, predominately through the use of AGC, to follow moment-to-moment changes in load. Regulation service is bid into the market by individual units that have AGC capability and wish to participate in the regulation market. Bid information includes regulation response rate (MW/min) and regulation availability rate ($/MW) .
