Title: Optimal meter placement and transaction-based loss allocation in deregulated power system operation
Author: Ding, Qifeng
Abstract: In this dissertation topics of optimal meter placement and transaction -based loss allocation in deregulated power system operation are investigated . Firstly , Chapter II introduces the basic idea of candidate measurement identification , which is the selection of candidate measurement sets , each of which will make the system observable under a given contingency (loss of measurements and network topology changes ) . A new method is then developed for optimal meter placement , which is the choice of the optimal combination out of the selected candidate measurement sets in order to ensure the entire system observability under any one of the contingencies . A new method , which allows a natural separation of losses among individual transactions in a multiple -transaction setting is proposed in Chapter III . The proposed method does not use any approximations such as a D .C . power flow , avoiding method induced inaccuracies . The power network losses are expressed in terms of individual power transactions . A transaction -loss matrix , which illustrates the breakdown of losses introduced by each individual transaction and interactions between any two transactions , is created . The network losses can then be allocated to each transaction based on the transaction -loss matrix entries . The conventional power flow analysis is extended in Chapter IV to combine with the transaction loss allocation . A systematic solution procedure is formed in order to adjust generation while simultaneously allocating losses to the generators designated by individual transactions . Furthermore , Chapter V presents an Optimal Power Flow (OPF ) algorithm to optimize the loss compensation if some transactions elect to purchase the loss service from the Independent System Operator (ISO ) and accordingly the incurred losses are fairly allocated back to individual transactions . IEEE test systems have been used to verify the effectiveness of the proposed method .
