Collaborative optimization of economic dispatch and reactive power dispatch

2019 Chinese Control Conference (CCC), 2019
Economic dispatch and reactive power dispatch are two important tasks in power systems, which respectively concern the economy and environmental friendliness and the safety and reliability of grid operation. Essentially different from the related literature with separately solving the two dispatches, this paper is devoted to collaboratively optimizing ...

Modified DE/Sin for economic dispatch and environmental dispatch

2018 5th International Conference on Business and Industrial Research (ICBIR), 2018
In this paper, the modified differential evolutionary with sine function is developed. This modified algorithm is applied to economic dispatch and environmental dispatch problem. The problem formulations are formulated as single objective function. The simple 6 units system is used as test system.

Economic and environmental power dispatch

European Journal of Operational Research, 1993
Abstract This paper reviews the operational research aspects of power dispatch since their inceptions to the present. The classic single criterion dispatch as well as new multicriteria approaches in dispatching, oriented both toward economy and avoidance of unacceptable environmental impact, are summarized.

Economic Load Dispatch

2018
The main objective of the power system is to deliver electric energy to its loads economically and efficiently in a safe and reliable manner. Due to the complicated structure of the present power system network and competitive environment introduced by deregulation, optimal power flow (OPF) and optimal reactive power flow (ORPD) provide efficient ...

Stochastic economic emission load dispatch

Electric Power Systems Research, 1993
Abstract The economic emission load dispatch (EELD) problem is a multiple non-commensurable objective problem that minimizes both cost and emission together. In the paper a stochastic EELD problem is formulated with consideration of the uncertainties in the system production cost and nature of the load demand, which is random.

Dynamic Economic Dispatch

2017
This chapter provides a solution for dynamic economic dispatch (DED) problem in GAMS. DED refers to dispatch a set of units over a given operating horizon (usually 24 h). The on/off status of units is assumed to be known. Two paradigms of DED are discussed and modeled, namely cost-based DED and price-based DED. Finally, the linearized version of DED is

Economic Load Dispatch Using PSO

2020
Nowadays, electrical energy is playing vital role in human life. The economic operation of the power system is always desirable and this can be achieved by economic load dispatch. The economic load dispatch means allocating the power to different generating units to minimize or reduce the total fuel cost satisfying the different power system ...

Analytical study on economic dispatch

2010 Chinese Control and Decision Conference, 2010
For economic dispatch of parallel power unit, the optimal essential qualification is proved by method of Kuhn-Tucker. And by adopting the function of the efficiencies and the power of the unit as a parabolic curve, it is proved that the sufficient condition of the economic dispatch.

Dynamic Economic Dispatch of Generation

IEEE Transactions on Power Apparatus and Systems, 1980
A set of procedures and algorithms are developed for dynamic economic dispatch of generation units. When coupled with a short-term load predictor, "look- ahead" capability is provided by the dynamic economic dispatch that coordinates predicted load changes with the rate-of- response capability of generation units. Dynamic economic dispatch also enables

Economic Dispatch in power systems

2015 IEEE 8th GCC Conference & Exhibition, 2015
Economic Dispatch is an important optimization problem in power system planning. This article presents an overview of the economic dispatch problem, its formulation, and a comparison of addressing the problem between the vertically integrated market and the liberalized market environments.
