Abstract
AbstractFor the well being of a system, different parameters are needed to be tested by system operators, among which congestion management is of one prime importance. Different forms of economic parameters are required to signals the congestion management, and the most sensitive signal being the locational marginal price (LMP). These LMPs are the change of price of energy at each bus in the congested power market. LMPs are solved using of shift factor (SF) techniques on DC-OPF (DC-Optimal Power Flow). The LMPs are primarily comprises of three parts viz. marginal energy price (MEP), marginal congestion price (MCP) and marginal loss price (MLP). In this paper, nodal prices that are actually the LMPs are calculated in a thirty (30) bus test case system, and it shows that the LMPs vary from bus to bus when the system is congested.KeywordsCongestionDC-optimal power flowLocational marginal priceShift factors
