in this paper, first, a new criterion, titled “surplus percent of the customers” is defined for static transmission expansion planning in restructured power systems. then by a simple example, the new criterion is compared with some already presented market-based criteria and it is shown that the new criterion can realistically evaluate the transmission network expansion from the market view. in...

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...

Electricity industries around the world have significantly restructured in order to improve their economic efficiency, reliability of power systems and accountability. Accurate prediction of day-ahead electricity nodal price has now become an important activity to address the system operations and price volatility in the restructured electricity market. This will facilitate the market participa...

with the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

in order to improve the reliability of the power system, sufficient amount of new capacity should be installed in the network. usually generation units’ payoff in an energy market is not adequate to cover their expenses. therefore, energy only market cannot induce investors to invest in generation field. due to energy only market inefficiency, a supplementary algorithm is suggested to cover the...

To date, a number of electricity markets have deregulated, relying on market forces to set prices. The results thus far are mixed. Therefore, policy makers must rely on ex ante analyses of the market power potential for generation owners. Recently, policy makers in the Wisconsin and Upper Michigan (WUMS) electricity market have contemplated deregulation. In this paper, we examine the ability of...

One of the major challenges in restructured power systems is to maintain a level of generation capacity that ensures an acceptable level of certainty against power interruptions. A power market with a wellfunctioning spot market and long-term markets for allocation of risks between consumers and producers should in theory generate optimal investments in new power generation capacity, but this m...

With the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

Congestion and overloads in transmission lines always is one of the basic problems in the power system operation. Some of the consequences of this problem in the restructured power system are sudden price increasing in some areas, increase in market power and reduction in the competition in the market. FACTS devices as an efficient, powerful and economical means can have a key role in transmiss...
