Comprehensive Optimization Model for Hydroelectric Reservoir Operations
The Energy Management and Maintenance Analysis (EMMA) model is used to maximize net revenues to Manitoba Hydro considering the operation of hydroelectric and thermal generation, generation...

Decision Support for Short Term Export Sales From a Hydroelectric System
A stochastic dynamic programming (SDP) model was recently developed and implemented at British Columbia Hydro and Power Authority (B.C. Hydro) to provide decision support for short term...

Use of Probabilistic Constraints in Reservoir Operation Policies With Sampling Stochastic Dynamic Programming
The role of mathematical simulation and optimization models in hydropower planning at Pacific Gas and Electric Company is discussed, and some of the models are described. Applications...

Hydropower Stochastic Forecasting and Optimization
A microcomputer package was implemented to support real-time decisions for weekly and month-end water management at an industrial complex in the mountains of British Columbia. The rolling...

Real-Time Hydrosystem Operations Using Probabilistic Balancing Rule Models
A Probabilistic Balancing Rule model is presented and shown to be effective in the prescription of real-time (daily) operations for a multi-purpose surface water reservoir system. In this...

Application of Principal-Component Analysis to Long-Term Reservoir Management
Determining the optimal long-term operating policy of a multireservoir power system requires solution of a stochastic nonlinear programming problem. The paper presents a very efficient...

Stochastic Control of Hydropower Systems
A two-level stochastic control method is presented for the real-time operation of hydropower projects. The first level assumes fixed turbine discharges and utilizes probabilistic inflow...

Stochastic Dynamic Programming Applied to Multireservoir Systems
The main goal of this work was to develop a large scale optimization algorithm incorporating the principle that the uncertainty of future events increases with time. This principle governs...

Brief Description of Castor Software for Management of Reservoir Systems
The CASTOR group, started in 1984 at Ecole Polytechnique de Montreal (Canada), is a major software development project for an integrated CAD system related to hydro projects. Based on...
