---------------------------------------------------------------------***--------------------------------------------------------------------Abstract In restructured electricity markets, an effective transmission pricing method is required to address transmission issues and to generate correct economic signals to reduce the generation cost. It is necessary to develop an appropriate pricing schem...

We consider combinatorial problems associated with contract satisfaction and market clearing arising in deregulated electrical power industry. A prototypical problem in this context can be stated as follows: Given a network and a (multi-)set of pairs of vertices in it denoting bilateral contracts, find the maximum number of simultaneously satisfiable contracts. The extension of the above proble...

Typically the cost of a product, a good or a service has many components. Those components come from different complex steps in the supply chain of the product from sourcing to distribution. This economic point of view also takes place in the determination of goods and services in wireless networks. Indeed, before transmitting customer data, a network operator has to lease some frequency range ...

Deregulated wholesale markets for bulk electricity supplies are likely to deviate from the perfectly competitive ideal in many areas where transmission losses, costs and capacity constraints isolate customers from the effective reach of many generators and limit the number of competitors. In those regions where a few suppliers or marketing agents dominate the market, prices may rise wellabove t...

The ISES Project – Information, Society, Energy, System – was started in 1996 and finished three years later, in 1998. The initial tasks for the project was to study in which way the fast expanding information technology would make energy distribution more efficient and at the same time create synergism with the growing information society by offering the electrical grid as a communication chan...

The computation of Total Transfer Capability (TTC) is a significant task in the deregulated environment. In this paper, Firefly (FF) algorithm is used to solve the Optimal Power Flow (OPF) based TTC problem. Real power output of generators in source area and real power load in drop area can be adjusted to obtain the maximum transfer capability. The value of TTC can be made more accurate by cons...

Electricity market plays an important role in improving the economics of electrical power system. Transmission network is vital entity in open access deregulated wholesale electricity market. Whenever transmission network congestion occurs in electricity market, it divides the market in different zones and the trading price of electricity will no longer remains the same for the whole system. Bi...

In the new deregulated electric power market, energy transactions are generally processed in terms of hourly energy delivery. Failing to fulfill energy delivery obligation may result in penaltalt to energy tiesprodp. This paper studies the relationship between generation level schedule, energy delivery schedule and physical ramp-rate of a generating unit. It is shown that although ramp-rate con...

In a deregulated power market, the optimum power flow (OPF) for an interconnected grid system is an important concern as related to transmission loss and operating constraints of power network. The increased power transaction as related to increased demand and satisfaction of those demand to the competition of generation companies (GENCOs) are resulting the stress on power network which further...

The aim of this paper is to compare the operational pattern of an energy storage system (ESS) in a vertically-integrated utility and in a deregulated market environment for different levels of wind integration. As the main feature of a vertically-integrated utility is a centralized decision-making process, all of the investment and operating decisions are made with a single goal of minimizing t...
