Due to complication of electric power technology, electricity transaction is in face of both market rule problems and technical problems. Equity argument often takes place when market rules conflict with technical constraints. Analysis reveals that unfair results are inevitable in some situations, but other situations may be handled more equitably by elaborately designing the market trading rules...
Under normal conditions, total transfer capability (TTC) mainly depends on voltage phase change, whereas power loss depends on reactive power distribution. The minimization of power loss is consistent with maximization of TTC. Based on this idea, TTC calculation can be divided into two sub-problems, namely (A) prediction of incremental TTC, which can be calculated by means of simplified linear lossless...
This paper adopts a Nash-Cournot game theoretic framework and uses a linear DC network to represent transmission constraints. The multi-dimensional Cournot game is presented and, the bilateral model of spatial market is built. Because of capacity constraints and Kirchhoff's laws, in this equilibrium model, the participants' strategy space is coupled. The market equilibrium is defined as a set of prices,...
In electricity markets, ISO has to purchase the proper reserve capacity at some price for maintaining an acceptable risk level of power system. At the same time, the responsibility of each market participant must be quantified explicitly for apportioning the costs of reserves. Unlike traditional deterministic dispatch, this paper maximizes the social welfare with considering the expected surplus of...
Demand response measure is very important to improve electricity market function. In order to maximize their profit, large industrial or commercial consumer prefers redistributing load between periods to reducing load absolutely in demand response program. Considering demand response in day-ahead generation scheduling then need to deal with more complicated coupling constraints. To solve the problem,...
