Dynamic Economic Emissions Dispatch

2021
This chapter analyzes the problem associated with assigning customer load demands to the available power-generating units to ensure a reliable and secured system. This determines the generation schedule of the available generating units to meet the forecast load demand over a period of time at a lower production cost while considering the ramp-up and ...

Economic Dispatch Reserve Allocation

IEEE Power Engineering Review, 1981
In 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

Frequency aware economic dispatch

2011 North American Power Symposium, 2011
In this paper we propose a unified economic dispatch and frequency control framework for power systems with an increasing amount of intermittent resources such as wind and solar. While the conventional hierarchies of power system decision and control are based on the time-scale separation principles (e.g., primary, secondary, and tertiary control), the

Security Constrained Economic Dispatch

International Journal of Operations Research and Information Systems, 2010
The main objective of electric power dispatch is to provide electricity to the customers at low cost and high reliability. Transmission line failures constitute a great threat to the electric power system security. We use a Markov decision process (MDP) approach to model the sequential dispatch decision making process where demand level and ...

Dynamic Economic Dispatch: Feasible and Optimal Solutions

IEEE Power Engineering Review, 2001
Dynamic 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.

Emission constrained economic dispatch

IEEE Transactions on Power Systems, 1994
This paper presents a methodology to include emission constraints in classical economic dispatch (ED), which contains an efficient weights estimation technique. Also, a partial closed form technique is presented to implement the emission constrained economic dispatch (ECED). A simple technique is proposed to identify the binding constraints.

Piecewise affine dispatch policies for economic dispatch under uncertainty

2014 IEEE PES General Meeting | Conference & Exposition, 2014
Stochastic optimization has become one of the fundamental mathematical frameworks for modeling power systems with important sources of uncertainty in the demand and supply sides. In this framework, a main challenge is to find optimal dispatch policies and settlement schemes that support a market equilibrium.
