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.

Optimization-based sale transactions and hydrothermal scheduling

IEEE Transactions on Power Systems, 1996
Selling and purchasing power are important activities for electric utilities because of potential savings. When a selling utility presents an offer including prices, power levels and durations, a purchasing utility selects power levels and durations within the offered range subject to relevant constraints.

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.

Hydrothermal scheduling using chaotic hybrid differential evolution

Energy Conversion and Management, 2008
This paper proposes a chaotic hybrid differential evolution algorithm to solve short-term hydrothermal system generation scheduling problem. In the proposed method, chaos theory is applied to obtain self-adaptive parameter settings in differential evolution (DE).
