In competitive electricity markets all over the world, an adoption of suitable transmission pricing model is a problem as transmission segment still operates as a monopoly. Transmission pricing is an important tool to promote investment for various transmission services in order to provide economic, secure and reliable electricity to bulk and retail customers. The nodal pricing based on SRMC (S...

the new competitive environment changes the paradigm of power system operation. in the transmission area, open access process provides fair accessibility for all market participants. congestion management is one of the most important side effects of this new process. this paper proposes a new approach for congestion management which is based on both active and reactive re-dispatch of the networ...

This paper proposes a pricing system for power system security in deregulated electricity market that includes voltage stability constraint in a multi-objective OPF problem. The OPF maximizes social benefit, as well as the distance from the voltage-collapse point. While pricing system security, ancillary service such as reactive power has been included. Effect of N–1 contingency on pricing is a...

capital asset pricing model (capm) has been among the common models to estimate expected returns rate. since the linearity assumption is considered in the standard version of the capital asset pricing model, estimating beta in nonlinear setting will be inconsistent and bias-oriented. therefore, this study tries to evaluate predictive power of nonlinear capital asset pricing model as well as sta...

<span lang="EN-US">Ancillary services in interconnected networks are crucial to secure real power transfers, maintaining network reliability, improving quality as well stability. Reactive has always been of special importance one the most substantial ancillary required control voltage grid. This paper presents a fresh reactive pricing approach by embedding variable transformer taps into a...

This paper proposes an index for nodal market power detection in power market under locational marginal pricing (LMP). This index is an ex-ante technique to detect the market power. More precisely, this criterion detects the potential of exercising market power regardless of detecting the actual market power. Also it is obvious that pricing and market clearing method affect the potential of exe...
