Abstract

Regulating system frequency is one of the most important system reliability management services that must be provided by market participants in a deregulated power system. The difference between load and generation due to contingencies or heavy variation of load, causes variation in frequency and this is required to be maintained within the normal operating band (NOB) as prescribed through various reliability standards adopted in various countries. However many energy setups are still experiencing frequency regulation issue due to energy shortage problems resulting in heavy losses for power companies and inconvenience to customers and Indian electricity system is one of them. But the Availability Based Tariff system adopted by India for the bulk transfer of power has succeeded in regulating the frequency to a greater level. In this paper an attempt has been made to develop a methodology based on the unscheduled interchange mechanism which is prevailing in India for Bulk power transfer to handle real time imbalances between supply and demand in a Deregulated market. This mechanism will work through independent generation units and loads that keep watch on system frequency and price signal and respond accordingly, thus eliminating the need for complex communication systems for control. Through this mechanism, we will not only be able to adjust system frequency close to nominal value but also it will help to achieve good savings. This technique is implemented on a 5 bus test system and it was found a lot of savings could be achieved by adopting this frequency regulation mechanism.
