This paper narrates an application of Particle Swarm Optimization (PSO) for economic load dispatch. The main objective function is to optimize the Fuel cost and Active power loss by considering the power flows within the allowable limits. The PSO is simple in concept and easy in implementation. It does not require any derivative information, sure and fast convergence. Moreover, the problem can ...
Optimal power flow (OPF) over power transmission networks poses challenging large-scale nonlinear optimization problems, which involve a large number of quadratic equality and indefinite quadratic inequality constraints. These computationally intractable constraints are often expressed by linear constraints plus matrix additional rank-one constraints on the outer products of the voltage vectors...
1. Abstract We consider an optimal control problem of optimal hydrothermal scheduling. The model, already discussed in [1], is deterministic and takes into account the dependence of efficiency of hydroelectric energy with respect to the volume of water in dams. The thermal cost is a strongly convex and nondecreasing function of the thermal power. We study the possible occurrence of a singular a...
Artificial Immune System is applied to determine the optimal hourly schedule of power generation in a hydrothermal system. A multi-reservoir cascaded hydroelectric system with a nonlinear relationship between water discharge rate, net head and power generation is considered. The water transport delay between connected reservoirs is taken into account. The transmission losses are also taken into...

The objective of this work was to develop a new design of an intake manifold through a 1D simulation. It is quite familiar that a duly designed intake manifold is essential for the optimal performance of an internal combustion engine. Air flow inside the intake manifold is one of the important factors, which governs the engine performance and emissions. Hence the flow phenomenon inside the i...
This paper aims to design an optimal distributed multi-agent controller for load frequency control and optimal power flow purposes. The controller parameters are optimized using Grey Wolf Optimization (GWO) algorithm. The designed optimal distributed controller is employed for load frequency control in the IEEE 30-bus test system with six generators. The controller of each generator is consider...

The weekly cost-optimal generation of electric power in a hydrothermal generation system is modeled as a multistage mixed-integer stochastic program. The model incorporates uncertainties of electrical load forecasts, of inflows to pumped storage hydro plants and of fuel or electricity prices. For its solution a stochastic Lagrangian relaxation scheme is designed by assigning (stochastic) multip...
The papers in the " Hydrothermal Vent " research topic cover a range of microbiological research in deep and shallow hydrothermal environments, from high temperature " black smokers, " to diffuse flow habitats and episodically discharging subsurface fluids, to the hydrothermal plumes. Together they provide a snapshot of current research interests in a field that has evolved rapidly since the di...
