An effective nodal price modeling is the key factor in managing transmission issues, which is able to generate correct economic signal. This paper examines the main idea behind the congestion-based nodal price modeling and further discusses the techniques used to incorporate transmission usage tariff into the model as a scheme of the authors' proposed models. In this comprehensive approach pricing...
Distributed generation (DG) has become increasingly popular in many power systems across the world. It is an effective approach to facilitate the usage of renewable resources for power generation purpose. However, the installation of DGs in a power system may change the pattern of the power flow and cause various complexities in the system. How to plan DGs to best utilize renewable energy source while...
Under voltage load shedding is an important approach for power system control subject to large disturbances. In this paper, a modal analysis based under voltage load shedding method is proposed. Detailed case studies are given to validate the proposed approach.
Bottlenecks on transmission line becomes an obstacle for the perfect competition of power market. One obvious drawback of such constraint is congestion. When congestion occurs, power market may be inefficient due to re-dispatch of generators connected to the grid. Energy prices vary throughout the network as generating costs raise in congested area, called locational marginal prices (LMP). In this...
Market operators are required to effectively manage transmission line, particularly as congestion occurs where energy prices are different at all nodes in the network. Locational marginal prices (LMP) have been extensively recognized as an appropriate solution in managing transmission congestion. This paper investigates formulation of LMP schemes using different approaches; DC optimal power flow and...
Basic concept of nodal price modeling in competitive market environment and some special considerations on its formulation are presented in this paper. Nodal prices represented by locational marginal prices (LMP) based settlement strategy is carried out in a deregulated market environment to establish the amount of money received by generation companies from system operator and paid to system operator...
