Electric Power Exchanges with Sensitivity Matrices An Experimental Analysis

چکیده
We describe a fast incremental method for power flows computation tailored for electric power markets. Fast in the sense that it can be used for real time power flows computation, and incremental in the sense that it computes any additional increase/decrease in line congestion caused by a particular (n-lateral) contract. Incremental methods offer a powerful way of dealing with congestion contingency, improve information flows among market entities, and are easy to understand. In this document we provide basic scaling properties for electric power markets using this method, and compare it with methods using (linearized) power flow code. The author is in the process of obtaining a patent on methods, algorithms, and procedures described in this paper.

متن کاملOptimal Decision Making Framework of an Electric Vehicle Aggregator in Future and Pool markets
Electric vehicle (EV) aggregator, as an agent between the electricity market and EV owners, participates in the future and pool market to supply EVs’ requirement. Because of the uncertain nature of pool prices and EVs’ behaviour, this paper proposed a two-stage scenario-based model to obtain optimal decision making of an EV aggregator. To deal with mentioned uncertainties, the aggregator’s risk...
