Under the deregulation of generation market, all distributed generators will participate in electric power bidding; therefore purchase cost problem has been getting more attention of power companies. However, under the competition principle, they can purchase energy from several of power generation companies, so there exist continuous and integral variables in purchase cost model. It is difficult...
This paper proposes a new method for allocating transmission loss in mixed pool and bilateral markets. The proposed method is based on an actual loss formula. In addition, the concept that the more the power is transferred, the larger the losses it should be responsible for is used. In this paper, power loss occurring in the pool market will be compensated by the representative generator and the loss...
This paper presented a marginal method allocating transmission losses to bilateral exchanges in the context of bilateral trading, based on the special relation between marginal loss comparative values for different slack buses. The advantage of this method is that the sharing results are irrelevant to the selection of slack bus, which is able to intuitively reflect the transmission distance of bilateral...
The paper considers the available alternatives of locating the thyristor-controlled phase angle regulator (TCPAR) in a deregulated power system. The problem of selecting the best location of TCPAR in the dispatch process of the competitive market is treated as a multicriteria decision-making process, which is solved using ELECTRE III method, which is a multicriteria decision-aid approach. The candidate...
This paper presents a new set of methodologies and tools to implement multilateral trades in a restructured electricity market. Loss minimization is made an objective, realized through elasticized transmission charge. This charge is designed to acts as a financial instrument that penalizes deviation from least loss formulation. To reduce its impact coalition formation is envisaged in a cooperative...
Some competitive power markets use marginal spot prices to assess energy transactions and to pay transmission service. The transmission revenue caused by network constraints under nodal marginal pricing is equal to network investment costs in ideal systems. However, in actual systems, marginal revenue is lower than network investment costs and complementary expansion charges should be paid by market...
One of the major problems in liberalized power markets is loss allocation. In this paper, a new method for allocating transmission losses to pool market participants is proposed. The proposed method is fundamentally based on Bialek's "Tracing the flow of electricity" method. The losses is allocated to market participants using the loss weight factors (LWFs) which are obtained from the square...
