This paper combines two previous techniques, reference independent LMP decomposition and fictitious nodal demand (FND), to achieve an improved LMP model. The combined model distributes system losses in each individual line such that there is no mismatch in every bus. Also, the reference independent LMP decomposition is still preserved..
A common practice for the Ex Post LMP calculation at a number of US ISOs uses a small constant range, typically from -2.0 MW to +0.1 MW, as each generator's lower and upper bounds. However, this paper shows that this common practice lacks theoretic justification and may lead to inconsistent results. For example, if the ex post dispatch results are identical to the ex ante dispatch schedules, it is...
A common practice for the Ex Post LMP calculation at a number of U.S. ISOs uses a small constant range, typically from -2.0 to +0.1 MW, as each generator's lower and upper bounds. This paper shows that this is an unjustified practice as the marginal units and LMP may change if the bounds are changed. A simple yet effective improvement is proposed.
In day-ahead power markets, the calculation of locational marginal price (LMP) relies on the load forecasting results. It is well known that short-term load forecasting results always contain certain degree of errors mainly due to the random nature of the load. At the same time, LMP step change exists at critical load level (CLL). Therefore, it is interesting to investigate the impact of load forecast...
In this paper, a brief review is firstly presented for Locational Marginal Price (LMP) calculation using the lossless DCOPF algorithm and the FND (Fictitious Nodal Demand)- based iterative DCOPF algorithm with losses considered. Also reviewed is the ACOPF model to calculate LMP. Then, a comparison of these three models is presented with the results from ACOPF as a benchmark. Simulation is performed...
Growth in electricity demand with lack of investment in new transmission facilities has led to the formation of load pockets with long congestion hours over transmission bottlenecks. When assessing resource adequacy with reference to the load pockets, one needs to include both generation resources and power delivery systems to capture their impacts on system reliability and market economics at the...
