Analysis of linear loss models — A New Zealand perspective

摘要: The New Zealand Electricity Market (NZEM) is a locational marginal price (LMP) market. market clearing engine, called Scheduling Pricing and Dispatch (SPD), based on security constrained DC OPF formulated as Linear programming problem (LPP). There are significant differences between how SPD calculates the LMPs at each node those calculated in many other LMP markets. In NZEM, which dual variable associated with power balance equality constraint captures all three cost components readily available solution. These of generation, losses network congestion. currently uses piece-wise linear loss model to capture branch. objective this paper present difference number segments, highlight problems encountered by such models.
