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...
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...
Congestion Management (CM) plays a significant role in power system operation under todaypsilas deregulated environment. Its two major functions are maintaining power system within security limits and collecting money from market participants paying back to transmission grid investors. This paper compares two market-clearing procedures for CM in terms of economic efficiency of the solution attained...
