Dynamic economic dispatch using the extended security constrained economic dispatch algorithm
IEEE Transactions on Power Systems, 1997An algorithm for solving the power system multi-stage dynamic economic dispatch (MDED) problem in real-time is presented. The MDED problem is formulated by formally adding ramp rate constraints to the extended security constrained economic dispatch (ESCED) problem for all stages beyond the first stage.

An Application of the Economic-Environmental Power Dispatch
IEEE Transactions on Systems, Man, and Cybernetics, 1977An application of a decision approach for controlling air pollution emission from power generation, presented by the authors in an earlier paper, is described. Trade-off curves between pollution emission and total operating cost are first computed for a portion of a realistic system containing coal, oil, and gas turbine generation.

Hierarchical Distributed Coordination for Economic Dispatch
2018 IEEE 27th International Symposium on Industrial Electronics (ISIE), 2018The classical economic dispatch problem faces difficult challenges in a future smart grid with a great many distributed generators and fast power fluctuations due to high percentage of renewable energy. The traditional centralized scheme can not cope with a large number of generators, and the convergence rate of the purely distributed control decreases

ECONOMIC ENVIRONMENTAL DISPATCH BY A MODE TECHNIQUE
Journal of Circuits, Systems and Computers, 2008Multi-objective differential evolution (MODE) is proposed to handle economic environmental dispatch problem, which is a multi-objective optimization problem (MOOPs) with competing and noncommensurable objectives. The proposed approach has a good performance in finding a diverse set of solutions and in converging near the true Pareto-optimal set ...

Distributed solution for the economic dispatch problem
21st Mediterranean Conference on Control and Automation, 2013A distributed approach for the economic dispatch of generating units is presented. It is assumed that the generators are connected by a communication graph. Each unit has information about itself, and can exchange information only with a few neighboring units in such a graph. Using graph theory and consensus algorithms, the proposed approach solves the

Distributed economic dispatch for power systems
2017 11th Asian Control Conference (ASCC), 2017The paper proposes a fully distributed approach for economic dispatch problem (EDP) in power systems. The goal is to determine the output power to meet the load demand economically. In this paper, a simple algorithm is proposed to solve EDP under capacity constraint. The proposed method only needs its local cost parameters and the local predicted load.

Modified DE/Sin for economic dispatch and environmental dispatch
2018 5th International Conference on Business and Industrial Research (ICBIR), 2018In 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.

Collaborative optimization of economic dispatch and reactive power dispatch
2019 Chinese Control Conference (CCC), 2019Economic 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 ...

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

Analytical study on economic dispatch
2010 Chinese Control and Decision Conference, 2010For 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.
