Scheduling of generation in deficit power systems
IEEE Transactions on Power Systems, 1988Scheduling studies are carried out on a deficit hydrothermal power system. The problem is formulated as one of minimizing the severity of power cuts. The maintenance schedule of the thermal plants is selected by minimizing its deviation from an ideal, unrealizable schedule.

Thermal power generation scheduling by simulated competition
IEEE Transactions on Power Systems, 1999This paper presents a new method for solving the unit commitment problem by simulation of a competitive market where power is traded through a power exchange (PX). Procedures for bidding and market clearing are described. The market clearing process handles the spinning reserve requirements and power balance simultaneously.

Neural networks for generation scheduling in power systems
[Proceedings 1992] IJCNN International Joint Conference on Neural Networks, 2003A neural network for generation scheduling in power systems is presented. The network consists of two levels which correspond to different types of variables in the generation scheduling problem. The first level is a neural net which solves economic dispatch, a sub-problem in the generation scheduling problem.

Realizability of Short-Term Power Generation Schedules
IFAC Proceedings Volumes, 1999Abstract In the current operation practice of electric power companies, hourly generation schedules obtained in short-term generation scheduling problems are taken as hourly energy delivery schedules. However, it is shown in this paper that hourly generation levels satisfying ramp-rate constraints may not be able to be realized as an energy delivery ...

A MATLAB-based power generator maintenance scheduler
IEEE PES Power Systems Conference and Exposition, 2004., 2005This paper presents a PC-based Windows application software package for production of optimised maintenance schedules, performing economic dispatch, predicting actual dates for long-term maintenance scheduling and querying the current status of a generating unit from data files.

Optimal Generation Scheduling of Hydrothermal Power Systems
IEEE Transactions on Power Apparatus and Systems, 1980In this paper decomposition and coordination techniques are applied to minimize the operation al cost of hydrothermal power systems. Through this for muXation large systems are dealt with by a more general and precise model that includes thermal operation costs and hydroelectric power generation as nonlinear functions, water head variations, stochastic

Short-term resource scheduling with ramp constraints [power generation scheduling]
IEEE Transactions on Power Systems, 1997This paper describes a Lagrangian relaxation-based method to solve the short-term resource scheduling (STRS) problem with ramp constraints. Instead of discretizing the generation levels, the ramp rate constraints are relaxed with the system demand constraints using Lagrange multipliers.

Tractable reserve scheduling in AC power systems with uncertain wind power generation
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017This paper presents a solution method for a day-ahead stochastic reserve scheduling (RS) problem using an AC optimal power flow (OPF) formulation. Such a problem is known to be non-convex and in general hard to solve. Existing approaches follow either linearized (DC) power flow or iterative approximation of nonlinearities, which may lead to either ...

Optimal scheduling of hydrothermal power generation in wholesale market environment
2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010Generation scheduling is an important component of power systems operation in a market environment. Electricity demand in different areas depends on local marginal prices in the wholesale market. The paper presents a model for mid-term optimization of electricity generation in the hydrothermal power systems.

A General Mathematical Programming Model for the Scheduling of Electric Power Generation
2014In this chapter a general mathematical programming model of the scheduling problem as formulated in Sect. 1.2 is presented for the case where the electric power generation system includes thermal plants only. The model is called general because no simplifying assumptions are applied for the sake of obtaining a mathematical programming model tractable ...
