Hydrothermal scheduling using chaotic hybrid differential evolution
Energy Conversion and Management, 2008This 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).

Multistage stochastic hydrothermal scheduling
2008 IEEE International Conference on Electro/Information Technology, 2008The paper addresses the stochastic long-term hydrothermal scheduling problem. This problem is usually modeled as a multistage stochastic program and solved using algorithms that are based on dynamic programming. One such algorithm is the stochastic dual dynamic programming (SDDP) algorithm, which is implemented for the hydrothermal power system of the ...

GENCO's Risk-Constrained Hydrothermal Scheduling
IEEE Transactions on Power Systems, 2008This paper presents a stochastic midterm risk-constrained hydrothermal scheduling algorithm in a generation company (GENCO). The objective of a GENCO is to maximize payoffs and minimize financial risks when scheduling its midterm generation of thermal, cascaded hydro, and pumped-storage units. The proposed schedule will be used by the GENCO for bidding

Hydrothermal Economic Scheduling
IEEE Transactions on Power Apparatus and Systems, 1963The theory of monotonic scheduling is extended to hydrothermal systems with interconnections to adjoining power systems. The exposition is limited to the two most common types of interconnection arrangements, although the methods can be applied to other cases as well.

An Efficient Hydrothermal Scheduling Algorithm
IEEE Power Engineering Review, 1987In this paper a Hydrothermal Scheduling Algorithm (HSA) for deterministic inflows is presented. A nonlinear network flow model representing the hydrothermal scheduling problem is used. By exploiting the special network structure, a temporally expanded arborescence [1], the HSA code attains important computational savings in processing time and memory ...

Optimal scheduling of hydrothermal systems
Proceedings of the Institution of Electrical Engineers, 1972The paper describes new algorithms based on 1st-order-gradient techniques for long-term and short-term scheduling of multistorage hydroelectric and multithermal systems for minimum operational cost, with system variables in discrete form, and water inflows and load demands as deterministic. Constraints on various para meters are duly taken into account.

Scheduling of hydrothermal power systems
IEEE Transactions on Power Systems, 1993The authors present a method for scheduling hydrothermal power systems based on the Lagrangian relaxation technique. By using Lagrange multipliers to relax system-wide demand and reserve requirements, the problem is decomposed and converted into a two-level optimization problem.

Optimal Scheduling Of Large Hydrothermal Power Systems
IEEE Transactions on Power Apparatus and Systems, 1985In this paper we present a new algorithm to find the optimal unit commitment and economic dispatch (UC/D) for a large hydrothermal power system. Mathematically, this is a large nonlinear, mixed integer optimization problem involving over 16,800 integer variables for a system having 100 thermal units with a 1-week scheduling horizon.
