In today’s restructured environment, congestion management plays an essential role in power system operation. Different methods are presented and discussed in this respect for congestion management in short-term and long-term intervals. It is attempted in the present paper to investigate the impact mechanism of FACTS devices and demand response programs together with generation re-dispatch as s...

Utilities participating in deregulated markets observe increasing uncertainty in load (i.e., demand for electric power) and prices for fuel and electricity on spot and contract markets. This study proposes a new formulation of the unit commitment problem of electric power generators in a restructured electricity market. Under these conditions, an electric power generation company will have the ...

This paper presents a model for optimisation of investments in new power generation within restructured power markets. We use stochastic dynamic programming to identify an optimal investment strategy when the objective is to maximize the expected profit over a long time horizon. This formulation of the investment problem takes into account the value of postponing the investment decision to wait...

Peru restructured its electricity sector in the early 1990s. In a short period of time and despite the fact that privatization has been limited, the Peruvian electricity sector already started to benefit from higher efficiency as evidenced by lower marginal costs and electricity prices, increased reliability as evidenced by declining transmission losses and improved service quality. On the othe...

-In this paper, an attempt has been made to establish a market mechanism for primary and secondary frequency regulation services in the restructured power system environment. The concept of elasticity of offer price and elasticity of offer quantity has been proposed. Such a design of offer structure helps the providers to respond to the system requirements based on the market price variations i...

In this paper, the impacts of an incentive-based Demand Response, i.e., Ancillary Service DR (ASDR), and a price-based DR, i.e., Time of Use (ToU), are revealed in a restructured power system which has some wind farms. This network is designed based on the pre-emptive market which is a day-ahead market with a balancing market prognosis. It is a proper mechanism to deal with the stochastic natur...
