Frequency constrained unit commitment
Energy Systems, 2015The Unit Commitment (UC) problem deals with the short-term schedule of the electrical generation to meet the power demand. The main objective is to minimize production cost, while respecting technical and security constraints. In addition to the system load, a specic amount of sparecapacity is committed to cope with uncertainties, such as forecasting ...

Unit commitment incorporating committed∕uncommitted reserve markets
IEE Proceedings - Generation, Transmission and Distribution, 2006A reserve market pricing while optimally committing units in a power system is considered with co-existence of committed and uncommitted reserve markets having different pricing schemes. Generators are optimally scheduled to meet the forecast load and their reserves are committed to satisfy the minimum spinning reserve criterion at the least offered ...

Unit Commitment With Flexible Generating Units
IEEE Transactions on Power Systems, 2005In today's volatile environment of restructured power markets, and with the passage of more stringent Clean Air Act Amendment of 1990, competitive generation units must have the ability for operating under flexible conditions to respond to various market driving forces.

Unit commitment is the process of deciding in advance whether to turn on or off each generator on the power grid at a given hour. In order to illustrate the changing nature of unit commitment as the electric power industry moves into a deregulated market, a broad form of the unit commitment problem for the present environment is first presented.

Sequential timestep unit commitment
2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002This paper presents a method for solving the unit commitment problem sequentially in time. By decomposing the problem in time, each timestep is solved individually using a free market model of the power system. The corresponding market clearing handles both energy demand, primary reserve demand and secondary reserve demand, and is performed using an ...

IEEE Transactions on Power Systems, 1992
The authors present a thermal unit commitment method for interconnected multiarea power systems. The method is a natural extension of the commitment utilization factor (CUF)-based single-area unit commitment method. CUF is extended to reflect the impact of multiarea transmission interconnection constraints on the utilization efficiency of committing a ...

Unit commitment literature synopsis
IEEE Transactions on Power Systems, 1994Several optimization techniques have been applied to the solution of the thermal unit commitment problem. They range from heuristics such as complete enumeration to the more sophisticated ones such as Augmented LaGrangian. The heuristics have even reappeared as expert systems.

IEEE Transactions on Automatic Control, 1977
The paper describes a new and rigorous method for determining the mode of operation of an electrical power system that minimizes the operational cost. The power system consists of M thermal generating units and one constant-head hydroplant. The operational cost includes the fixed and variable start-up and running costs of the thermal units.

Fuel constrained unit commitment
IEEE Transactions on Power Systems, 1992The authors present a generalized method of solving the unit commitment problem with fuel constraints. The fuel-constrained unit commitment problem is decomposed into a linear fuel dispatch (FD) problem and a unit commitment (UC) problem. The FD problem optimizes system fuel cost while satisfying fuel constraints and unit fuel requirements.
