Abstract: | The electric supply industry across the globe has witnessed newlineconvincing changes in its organization and management for the past three newlinedecades. The motivation for operational and organizational changes of this newlinederegulated industry and the regulatory regime is generally driven by a desire newlineto make electric sector more efficient through competition. Competitive newlinemarket provides the driving force for the generators to operate in its most newlineefficient and economic manner in order to derive most of the customer newlinefocused benefits as well. newlineHowever, operation and control of restructured electricity markets newlinepose more complex and technical challenges than the conventional newlinemonopolistic market structure. This thesis has mainly addressed the issues of newlineAvailable Transfer Capability (ATC) determination, sensitivity of network newlineuncertainties on ATC calculation, electricity transmission pricing and newlinetransmission congestion management. newlineThe ATC of a transmission network refers to its unutilized transfer newlinecapability available for further commercial activity over and above the newlineexisting transfer commitments. ATC in an electricity market is required to be newlineupdated dynamically based on the actual operating conditions. For the newlineaccurate and fast determination of ATC, network sensitivity based methods newlineutilizing DC power transfer distribution factors and AC power transfer newlinedistribution factors are being used. However, these factors provide quite newlineinaccurate results as they are calculated based on the real power flow alone in newlinethe transmission lines. The role of reactive power flow in the line loading has much significance and this might drive the computation to wrong or at least newlineunreliable ATC results. In this regard, a novel non-iterative approach is newlineproposed to calculate ATC under system intact mode and Contingent ATC newline(CATC) under (n-1) line outage contingency mode of operation using newlineApparent power Transfer Distribution Factors (STDFs) and Line Outage newlineApparent power Transfer Distribution Factors (LOSTDFs) respectively. newline |
