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 ...

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.

Dynamic Economic Dispatch: Feasible and Optimal Solutions
IEEE Power Engineering Review, 2001Dynamic economic dispatch is an extension of the conventional economic dispatch problem that takes into consideration the limits on the ramp rate of the generating units. This paper examines the factors that affect the feasibility and optimality of solutions to this problem. It proposes two new solution methods.

On-line secure and economic dispatch
Electric Power Systems Research, 1979Abstract This paper describes the application of an on-line economic dispatch control program with security constraints including outage-contigency constraints. The program is designed to run on average every 30 s with a small power system and gives feasible solutions with respect to constraints on control variables (real power generation, except in

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 Dispatch Reserve Allocation
IEEE Power Engineering Review, 1981In this paper, the economic dispatch problem is reformulated to include a constraint on the maximum average system frequency deviation of a power system following a postulated disturbance. The economic dispatch problem is translated into a well-defined nonlinear mathematical programming problem whose solution is obtained by solving a sequence of linear

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 ...

Dynamic Economic Dispatch of Generation
IEEE Transactions on Power Apparatus and Systems, 1980A 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
