Market power, defined as the ability to raise prices above competitive levels profitably, continues be a prime concern in restructured electricity markets. power must mitigated improve market performance and avoid inefficient generation investment, price volatility, overpayment systems. For this reason, involving transmission expansion planning (TEP) problem is essential for ensuring efficient ...

The role of Independent System Operator (ISO) in the restructured power industry includes system control, capacity planning, transmission tariff and congestion management; the challenging task being minimizing the congestion. One of the popular techniques used to alleviate congestion is using Flexible AC Transmission Systems (FACTS) devices. The power system generally operates near its rated ca...

Congestion Management (CM) is a very important aspect of present deregulatory power environment. In the restructured power market congestion occurs when the transmission network is unable to accommodate all the desired transaction due to violation of system operating limit. Increase of real power loss, increase of load demand compared to generated power, lack of Var sources or the fall of volta...

Automated Metering Infrastructure (AMI) is a energy technology that would allow consumers to exhibit price elasticity of demand under smart-grid environments. The market power of the generation and transmission companies can be mitigated when consumers respond to price signals. Such responses by consumers can also result in reductions in price spikes, consumer energy bills, and emissions of gre...

Power system security and reliability have become challenging issues in the present restructured scenario. Nowadays, power systems are forced to operate under stressed operating conditions closer to their security limits due to increased loading and large interconnections. Under such fragile conditions, any small disturbance could endanger system security particularly in contingency conditions ...

Wind generation with an uncertain nature poses many challenges in grid integration and secure operation of power system. One of these operation problems is the unit commitment. Demand Response (DR) can be defined as the changes in electric usage by end-use customers from their normal consumption patterns in response to the changes in the price of electricity over time. Further, DR can be also d...

The objectives of load frequency control (LFC) are to minimize the transient deviations in these variables (area frequency and tie-line power interchange) and to ensure their steady state errors to be zeros. Since the tieline interfaces give rise to weakly coupled terms between areas, the large-scale power system can be decentralized into small subsystems through treating tie-line signals as di...

In restructured power systems, planning unit commitment includes optimization of production sources in order to maximize the profit of power producing corporations (GENCO) with conforming to the related limits, which is introduced as the planning based on the profit of units commitment (PBUC). In this paper, the algorithm of Iteration Particle Swarm Optimization (IPSO) has been used in order to...
