CALCULATIONS OF ELECTRICAL POWER COST IN RESTRUCTURED POWER SECTOR: A CASE STUDY
Main Article Content
Abstract
This paper presents different methods for electrical cost of transmission and distribution to its customer through different transactions under restructured environment of Electrical power sector. There are different methods for calculate the cost on the basis of various criteria. In this paper explanation of different methods is given and tries to explain the best of them. There is IEEE 9 bus system is considered for the calculations. For the calculation of rate some transaction assumed on different buses and load is taken. This transaction is used in Megawatt. These transactions are bilateral and free from the direction of power flow direction, reactive and active power both are considered and power factor of the system included. Calculation of the flowing power at the different busses using load flow has been calculated. Load flow calculation provide power flow in transmission line and this power can use for the calculation of the cost of transmission power. After that we can calculate the price of electricity with different transaction on different values and without transaction. Auction system or mechanism is used in restructured electrical power sector for transparent and better than other way to calculate electricity cost.
