Value of Var Support in a Competitive Environment

چکیده
This paper presents a method for allocation and evaluation of reactive power (VAr) support contracts necessary to maintain system security and quality of supply. The method also quantifies the value of VAr support from individual generators or a portfolio of generators. Such information may be useful both to generating companies in preparing VAr tenders and to the market operator in assessing the value of VAr support tenders. For this purpose a novel sensitivity analysis based security constrained OPF (SA-SCOPF) is described that caries out the evaluation of VAr support offered from various generators across several demand levels taking into account a number of contingent systems. Case studies are presented to demonstrate the performance of the developed solution scheme of the SA-SCOPF on the England and Wales 1092 bus network.

In this seminar we show clean comparisons between EnKF and 4D-Var made in Environment Canada, briefly describe the Local Ensemble Transform Kalman Filter (LETKF) as a representative prototype of Ensemble Kalman Filter, and give several examples of how advanced properties and applications that have been developed and explored for 4D-Var can be adapted to the LETKF without requiring an adjoint mo...
متن کاملEvaluating Interest Rate Covariance Models within a Value-at-Risk Framework
We find that covariance matrix forecasts for an international interest rate portfolio generated by a model that incorporates interest-rate level volatility effects perform best with respect to statistical loss functions. However, within a value-at-risk (VaR) framework, the relative performance of the covariance matrix forecasts depends greatly on the VaR distributional assumption. Simple foreca...

In this paper, we study intrinsic vs. extrinsic motivation in players playing an electrical engineering gaming environment. We used UNTANGLED, a highly interactive game to conduct this study. This game is developed to solve complex mapping problem from electrical engineering using human intuitions. Our goal is to find whether there are differences in the ways anonymous players solved electrical...
متن کاملA New Approach to VAr Pricing and Control in the Competitive Environment
This paper develops a price structure for providing reactive power service and control based on optimal power flow (OPF) approach. The cost of reactive power support service is determined based on capability and contributions to the improvement of system performance such as security, reliability and economics, by computing sensitivity of objective function with respect to reactive power support...
