Available Transfer Computing Capability with the Generator Participation Factor

One of the objectives of deregulation is to create competitive markets to trade electricity. So as to supply the loads under optimal conditions, generating companies with cheaper power are preferred to transmit their power over the transmission network. The transmission network has a complexity of transactions in a deregulated power system. Complexity in transactions through different paths of the transmission network are the root cause of accidents, and due to the volatile nature of electricity as a commodity, it will be further enhanced. Real-time control of power transactions along the transmission path is predominantly required due to its inability to store electricity and disposition to accidents that are difficult to fix. All generators are able to transfer electricity into the system thanks to open access, however this may cause one or more lines to run over their design parameters, resulting in network congestion. Accurately estimating the available transfer capacity (ATC), which is the amount of transfer capacity still available in the system for future transactions, is one of the biggest issues. This paper describes the evaluation of ATC using Power Transfer Distribution Factors and Participation Factors. The participation factor is a measure of how the real power output of the generator changes in response to load demand. In this paper, by choosing different generator participation factors, its impact on ATC is observed using Power Word Simulator14. The solutions obtained are useful in the present restructuring environment.
