Reliability investigation has always been one of the most important issues in power systems planning. The outages rate in power system reflects the fact that more attentions should be paid on reliability indices to supply consumers with uninterrupted power. Using reliability indices in economic dispatch problem may lead to the system load demand with high reliability and low probability of powe...

This paper addresses the problem of reducing CO2 emissions by applying convex optimal power flow model to the combined economic and emission dispatch problem. The large amount of CO2 emissions in the power industry is a major source of global warming effect. An efficient and economic approach to reduce CO2 emissions is to formulate the emission reduction problem as emission dispatch problem and...

There are two significant issues with the incorporation of smart grid technology in power system operating studies including economic emission, unit commitment problem (UCP). Economic dispatch (EDP) is a UCP sub-problem which find optimum output for given combination running units. When using electro-energy systems to strategically distribute produced by all plants, especially important. Pumped...

The smart grid recently has been a vital research field among the global researchers and academia due to its significant transformation of the traditional, original and aging power grid networks. This paper reviews the state of the potentials of a smart distribution grid and highlights relevant areas of research problems that are related to the optimal sizing, unit commitment, and economic disp...

The Combined Heat and Power Economic Emission Load Dispatch (CHPEED) is an optimization problem to minimize the cost and emission while ensuring the fulfilling the power and heat demand and feasible constraints. This paper presents Particle Swarm Optimization (PSO) technique and other to solve CHPEED with bounded feasible operating region. The main potential of this technique is that it proper ...

The paper investigates the performance of proposed search technique for different kinds of economic dispatch problems by searching generation pattern of committed units in polar coordinate system being projection of phasor on real axis with respect to its displacement. A slack generator is introduced to meet the demand constraint while generation pattern is searched within operating limits of g...

This paper presents an efficient emission constrained economic dispatch algorithm that deals with nonlinear cost function and constraints. It is then incorporated into the dynamic programming based hydrothermal coordination program. The program has been tested on a practical utility system having 32 thermal and 12 hydro generating units. Test results show that a slight increase in production co...

To design a class of time-varying economic dispatching algorithms for smart grids based on the Lagrangian dual idea load problems that arise in practical applications grids, and to demonstrate convergence algorithms.
