In this paper, a new reactive power market clearing (RPMC) mechanism for day-ahead competitive electricity market is developed based on multi-objective optimization approach. In proposed mechanism, three objective functions such as total payment function (TPF) for reactive power support from generators and synchronous condensers, total real transmission loss (TRTL) and voltage stability enhance...

This paper expands a model different from existing models to analyze the cost and benefit of areinforced concrete solar chimney power plant (RCSCPP) built in the desert regions of Iran.Based on the model and some assumptions for values of parameters, this paper calculates totalnet present value (TNPV) and the minimum electricity price in each phase by dividing the wholeservice period into four ...

The control architecture for well functioning open electricity market of smart grids is introduced. The novel concept is that it establishes near real-time market operators for smart grids. In the proposed market model, traders, producers, brokers and end-users are incorporated. It develops near realtime active and reactive power dispatch policies based on optimal operation of players. In reali...

New types of optimization problems are faced by the generating companies that operate in the Italian electricity market. The characteristics of these problems depend on the various market structures. In the framework of the recently-settled Italian electricity market, one of these new problems is the transition from hourly energy programs, defined by the market, to more detailed power generatio...

Due to the Deregulation of electricity industry, the competition is growing day by day between the Generators as well as in Distributors. But due to the competition in electricity market, it may cause congestion in the transmission lines and can cause black out in any area. This will affect not only the generation of electricity but also the consumers. To avoid this problem, in competitive elec...

This paper investigates the weather-driven performance of electricity markets in the operational time frame. Employing the probability distribution fitting approaches, weather impacts on power generation and electricity demand are modeled and assessed through processing large volume of historical data sets. Several novel weather-impact indices are proposed in this paper to evaluate the vulnerab...

Using a linear complementarity approach, we simulate the Japanese wholesale electricity market as a transmission-constrained Cournot market. Following Hobbs (2001), our model adopts the Cournot assumption in the energy market and the Bertrand assumption in the transmission market. The Bertrand assumption means that generators consider transmission charges as being exogenous, which can be interp...

This paper proposes a novel reactive power dispatch model that takes into account both the technical and economical aspects associated with reactive power dispatch in the context of the new operating paradigms in competitive electricity markets. The main objective of the proposed model is to minimize the total amount of dollars paid by the system operator to the generators for providing the req...

This paper presents an overview on development of cost effective wind power generation system. This work motivates for development of a model for hybrid system to investigate the combined operation of wind’s stochastic nature for imbalance minimization and optimal operation. Development of model for trading power in competitive electricity market and development of strategies for trading in ele...

In the Ontario power system, almost all coal power plants have been recently closed. The major power generation in Ontario is currently provided by nuclear power plants (base-load generation). Additionally, wind generation typically is maximum at night, a time period when the demand is minimum. This raises the question whether energy storage systems (ESSs) should be deployed in Ontario to shift...
