This Study Committee collates HVDC performance reports from power utility companies worldwide, to be later published in a biennial compendium which is distributed to all the participating utilities. It was envisaged that such information could be useful in the planning, design, construction and operation of new HVDC projects. It was also envisaged that the sharing of the operational performance data could be of benefit to those concerned with the operation and maintenance of existing HVDC schemes or those planning to build new HVDC links. For the period from 1 January to 31 December 2002, a report on the operational performance of the Malaysia-Thailand 300/600 MW HVDC interconnection project was prepared jointly by the designated \"system correspondences\" from Tenaga Nasional Berhad (TNB) and the Electricity Generating Authority of Thailand (EGAT). This paper highlights some of the more important operational parameters calculated and reported to CIGRE, including the energy utilization of the HVDC scheme, energy availability and unavailability and scheduled and forced outages.","PeriodicalId":136640,"journal":{"name":"Proceedings.

Nonlinear control approach based on feedback linearizing scheme for FACTS devices has been proved in previous literature to have superior performance In damping the electromechanical oscillations of the power system. In this proposed control scheme, the artificial neural network (ANN) will be trained based on feedback linearization control scheme. Radial basis function neural networks (RBFNN) are used as online approximators to learn the unknown dynamics of the system. However, steady state error after the disturbances occurs in conventional feedback linearizing controller. Thus, training of RBFNN as conventional feedback linearizing controller became unrealizable. Consequently, fuzzy controller based on TSK IV control scheme has been used to filtered out the steady state error. This proposed controller is expected to approximate and replace complex mathematical equations of feedback linearization control scheme. To demonstrate the application of the proposed controller, case studies are done with a single-machine infinite-bus power system with current source inverter (CSI)-based STATCOM installed at certain bus. The efficacy of the control strategy is evaluated by digital computer simulation studies using MATLAB under various transient disturbances and a wide range of operating conditions. The approximated control signals are compared with that of targeted control signals to exhibit the elegance of the proposed control scheme.","PeriodicalId":136640,"journal":{"name":"Proceedings.

Transmission access pricing must be nondiscriminatory, transparent, economically efficient, and allow full recovery of costs. In the case of electricity transmission system, economic efficiency implies promoting an optimal utilisation of existing network, efficient siting of new generations and loads and promoting transmission investments. These characteristics require that the transmission circuits that pertain to each transaction must be identified and their costs properly allocated among users. Therefore, cost allocation is a major issue in transmission access pricing and has given rise to a lot of methodologies. This paper presents an overview of MW-Mile method of transmission cost allocation. Under MW-Mile method there are a number of variants in relation to how the cost of each circuit is allocated to the various users of the circuit. All these various allocations of costs under MW-Mile method categorized as absolute, reverse, dominant and extended methods are tested, compared and analysed using the Malaysian power system in order to assess their impact on the long-term transmission planning. Focus is given to observe which cost allocation method that can provide strong siting signals.","PeriodicalId":136640,"journal":{"name":"Proceedings. National Power Engineering Conference, 2003.
