This paper proposes a new Hybrid Fuzzy Dynamic Velocity Feedback Particle Swarm Optimization (HFDVF-PSO) for solving Economic Dispatch (ED) problem with non-smooth cost functions considering valve-point effects and multiple fuel options. In the proposed HFDVF-PSO method, the inertia weight is dynamically and nonlinearly adjusted to obtain better balance between global and local search abilities of...
This paper presents an application of Particle Swarm Optimization with Time Varying Acceleration Coefficients (PSO-TVAC) algorithm for Congestion Management (CM) using optimal re-scheduling of real power generation. The optimal rescheduling of powers in a pool model is formulated as a constrained nonlinear optimization problem. The PSO-TVAC algorithm is proposed to assess the generation re-schedule...
The first real time task of ISO focuses on Static Congestion Management (SCM), i.e. the congestion caused by the thermal and voltage limits. When power systems undergoes discrete changes in system configuration due to outage and contingencies, the system dynamic performance will be affected and the system stability might be threatened. In this respect, the second real time task of ISO focuses on the...
In a deregulated electricity market one of the most important tasks of independent system operator (ISO) is to manage congestion as it threatens system security and may cause rise in electricity price resulting in market inefficiency. In corrective action of congestion management schemes, it is crucial for ISO to select the most sensitive generators to re-schedule their real and reactive powers optimally...
In a deregulated electricity market transmission congestion occurs when there is insufficient transmission capacity to simultaneously accommodate all requests for transmission service within a region. One of the most important tasks of independent system operator (ISO) is to manage congestion as it threatens system security and may cause rise in electricity price resulting in market inefficiency....

In a competitive electricity market, he most important tasks of congestion management requires the Independent System Operator (ISO) to identify and relieve congestion as it threatens system security and may cause rise in electricity price resulting in market inefficiency. In corrective action of congestion management schemes, it is crucial for ISO to select the most sensitive generators to re-schedule...
