Hopfield Lagrange for short-term hydrothermal scheduling

2005 IEEE Russia Power Tech, 2005
This paper proposes Hopfield Lagrange (HL) model for optimal scheduling of fixed head and variable head hydrothermal coordination. HL is a combination of Hopfield neural network and Lagrange function. Unlike Hopfield network, HL is not required to define an energy function and map the problem into the Hopfield neural network with connection conductance.

Short-Term Scheduling

2009
In this chapter, the concept of the state sequence network (SSN) representation, which is the cornerstone of the material entailed in this textbook, is presented. This representation is based on states only, eliminating the use of tasks and units.

Short-term scheduling in multiprogramming systems

Proceedings of the third symposium on Operating systems principles - SOSP '71, 1971
This paper defines a set of scheduling primitives which have evolved from multiprogramming systems described by Dijkstra, Lampson, Saltzer, and the present author. Compared to earlier papers on the same subject, the present one illustrates a more concise description of operating system principles by means of algorithms.

Short-term scheduling of reactive power controllers

IEEE Transactions on Power Systems, 1995
A two-level approach is presented to solve the problem of 'optimal' short-term (one day) scheduling of reactive power controllers in this paper. The entire problem is decomposed into two levels: the master and the slave levels. The master level deals with minimization of the depreciation cost of compensators and EHV transformer taps in order to reduce ...

Short term generation scheduling with security constraints

IEEE Transactions on Power Systems, 1988
The authors discuss network flow concepts as a means of modeling a large multiriver system with cascaded hydro plants for purposes of generation scheduling. The reservoir dynamics are described by network flow balance equations. A nonlinear modeling approach is taken to represent hydro-plant generating characteristics, and variable reservoir heads are ...

Parallelized Stochastic Short-term Hydrothermal Generation Scheduling

2016 IEEE Power and Energy Society General Meeting (PESGM), 2016
This paper proposes a Stochastic Mixed-Integer Linear Programming (SMILP) formulation for Short-Term Hydrothermal Generation Scheduling (STHTGS) under uncertainty. STHTGS seeks to minimize present and future operation costs by deciding the commitments of thermal generators and the allocation of hydro resources during the planning horizon.

Short Term Hydrothermal Scheduling Using Reinforcement Learning

2019 IEEE International Conference on Intelligent Techniques in Control, Optimization and Signal Processing (INCOS), 2019
An optimal solution to the problem of hydrothermal scheduling, using Reinforcement Learning, is presented in this paper. The objective is to minimize the cost of the thermal unit, by making use of the available hydropower, subjected to various equality and inequality constraints.

Short-Term Scheduling of Combined Cycle Units

IEEE Transactions on Power Systems, 2004
Combined cycle units represent the majority of new generating unit installations across the globe. Combined cycle units feature distinct advantages for power generation such as high efficiency, fast response, shorter installation time, abundance of gas, and environmental friendliness.

Fast Evolutionary Progranuning Techniques for Short-Term Hydrothermal Scheduling

IEEE Power Engineering Review, 2002
Fast evolutionary programming techniques are applied for the solution of a short-term hydrothermal scheduling problem. Evolutionary programming (EP)-based algorithms with Gaussian and other mutation techniques have been developed and tested on a multi-reservoir cascaded hydroelectric system having prohibited operating zones and a thermal unit with ...

Neutral Search Technique for Short-Term Pump Schedule Optimization

Journal of Water Resources Planning and Management, 2010
This paper deals with the computation of short-term (typically 1 day ) least-cost pump schedule for water distribution systems with on-off type pumps and well-defined operating points. The objective function is to minimize the overall energy charge for a prescribed water consumption while several constraints are considered, such as storage and source ...
