In this paper, a new technique based on particle swarm optimization (PSO) is proposed to incorporate voltage stability limits into traditional optimal power flow (OPF) formulations. Two objective functions such as fuel cost and voltage stability margin (loadability) are considered to be optimized. In proposed method systempsilas maximum loading margin (loadability) is calculated by continuation power...
Competitive bidding for energy and ancillary services is increasingly recognized as an important part of electricity markets. On the other hand, the transmission capacity limits should be considered to optimize the total market cost. In this paper, a new approach based on Constrained Particle Swarm Optimization (CPSO) is developed to address the multi-product and multi-area electricity market dispatch...
This paper proposes an approach for optimal placement of STATic synchronous COMpensator (STATCOM) in power systems. The approach is based on the simultaneous application of particle swarm optimization (PSO) and continuation power flow (CPF) in order to improve voltage profile, minimizing power system total losses and maximizing system loadability with respect to the size of STATCOM. Simulation results...
The main purpose of an electric power system is to generate and supply a sinusoidal voltage to a large number of customers (residential, commercial and industrial). Ideally the supplied voltage is considered as a perfectly sinusoidal voltage of constant amplitude and frequency. In practice, the use of non-linear and time varying elements by the customers causes various deviations from the ideal sinusoidal...
