In this work, the most common problem of the modern power system named optimal power flow (OPF) is optimized using the novel meta-heuristic optimisation algorithm Ant Lion Optimizer (ALO). ALO is inspired by the hunting mechanism of Ant Lions in the natural environment. ALO has a fast convergence rate due to use of roulette wheel selection method. In order to resolve the optimal power flow problem,...
Pollution of the power plant has caused harmful environmental effects due to the emission of greenhouse gas. The pollution can be reduced by adjusting the real power outputs of different power plants. However, the relocation of real power outputs results an additional outlay in the system. In order to eliminate the conflict between the cost and emission, an optimal power flow is introduced in this...
In this paper, a security constrained power dispatch problem for a lossy electric power system area including limited energy supply thermal units is modeled in such a way that the modified subgradient algorithm based on feasible values (F-MSG algorithm) can be used to solve it. This model considers bus voltage magnitudes and phase angles, off-nominal tap ratios (once there are off-nominal tap changing...
In this paper, the modified subgradient algorithm based on feasible values (F-MSG) is applied to a security constrained environmental/economic dispatch problem for a power system area including limited energy supply thermal units. A nonlinear programming model is set up for the problem solution. Power system transmission loss is inserted into this model as equality constraints via load flow equations...
