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...
Optimal Operational Analysis of the Colorado-Big Thompson Project
The Northern Colorado Water Conservancy District is currently investigating the feasibility of constructing a major water storage project on the mainstem of the Poudre River for water...
Optimal Control of the West Parisian Area Water Supply Network
The West Parisian Area regional office of Lyonnaise des Eaux has been equipped with computer-aided optimal decision-making software, using daily water demand forecasts. This tool calculates...
Optimal Allocation of Water for Irrigation and Hydropower
This study examines how hypothetical changes in irrigation practices affect downstream hydropower sites. Dynamic programming and simulation techniques are coupled to determine optimal...
Optimal Real-Time Pump and Irrigation Scheduling for Center-Pivot Sprinkler Systems
A comprehensive scheduling algorithm is presented for optimally integrating irrigation and pump operational decisions in center-pivot sprinkler systems. Dynamic programming successive...
Meeting Environmental Commitments at Power Plants Using Real-Time Reservoir Scheduling
This paper describes two different real-time modeling systems that determine if scheduled hydro releases will affect meeting environmental commitments. The modeling system for John Sevier...
Energy Relations for Suspended Sediment Transport
One of the main difficulties in predicting transport rates of suspended sediment on the basis of the Rouse-expression for relative sediment concentrations, is the lack of any reliable...
Calibration of a Movable Bed River Model
This paper discusses the calibration procedures used for a model study of three miles (5km) of the Arkansas River. A hydro-power station will be added to an existing Corps of Engineers...
