Hydrothermal Scheduling Using Benders Decomposition: Accelerating Techniques

IEEE Transactions on Power Systems, 2007
A new decomposition method is presented that includes the network through ac modeling within the hydrothermal scheduling optimization process including the losses. In short-term hydrothermal scheduling, the transmission network is typically modeled with dc power flow techniques.

Short term hydrothermal scheduling under bilateral contracts

2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002
This paper aims to analyze the optimal short term scheduling of hydrothermal systems under pool-bilateral power markets. For that, the short term hydrothermal problem is modified by the inclusion of bilateral power transactions and the split of the vectors of power generations and loads into two components: one traded through the pool and the other ...

Evolutionary optimisation method for multistorage hydrothermal scheduling

IEE Proceedings - Generation, Transmission and Distribution, 2002
An evolutionary method is proposed for minimising the operational cost in the scheduling of hydrothermal systems with multiple storage. The method combines the advantages of constructive dynamic programming and evolutionary programming. Instead of evolving the primal variables such as water releases and thermal generator outputs, it evolves the ...

Optimal stochastic scheduling of hydrothermal systems

Proceedings of the Institution of Electrical Engineers, 1973
The paper describes an efficient algorithm, based on a 1st-order gradient technique in conjunction with a nonlinear-programming technique, for the long-term scheduling of multistorage hydroelectric and multithermal systems for the minimum expected fuel cost under the constraints of expected water available for hydroelectric generation in a given period

Improved PSO for short term hydrothermal scheduling

International Conference on Sustainable Energy and Intelligent Systems (SEISCON 2011), 2011
This paper addresses short-term scheduling of hydrothermal systems by using Particle Swarm Optimization (PSO) algorithm. Particle Swarm Optimization is applied to determine the optimal hourly schedule of power generation in a hydrothermal power system.

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.

Economic Environmental Scheduling of Hydrothermal Power System

Journal of The Institution of Engineers (India): Series B, 2014
This paper presents an interactive fuzzy satisfying method based on simulated annealing technique to determine the economic environmental scheduling of hydrothermal power system consisting of multi-reservoir cascaded hydro plants with time delay and thermal plants with nonsmooth fuel cost and emission level functions.

Genetic algorithms applied to hydrothermal system scheduling

POWERCON '98. 1998 International Conference on Power System Technology. Proceedings (Cat. No.98EX151), 2002
This paper presents a new method to solve the optimal scheduling of hydrothermal power systems (HPSs). This is performed using an artificial intelligence technique, genetic algorithms (GAs). A few tests have been carried out on a subsystem of the Southeast Brazilian System.

A network flow algorithm for hydrothermal scheduling

POWERCON '98. 1998 International Conference on Power System Technology. Proceedings (Cat. No.98EX151), 2002
This paper presents a new primal-dual algorithm, which is capable of solving nonlinear network flow problem with convex separable cost. One of the main characteristics of the algorithm is that it can begin with any circulation, feasible or not, provided that node conservation conditions are satisfied. Furthermore, this paper introduces how to apply the
