Systems Analysis for Fisheries Protection and Mitigation at Corps of Engineers Columbia River Dams
Pacific Northwest anadromous salmon and steelhead that migrate to and from the ocean are greatly affected by the numerous Columbia and Snake River dams they have to pass, first downstream...

Power System Study to Determine Hydro Benefits
This paper discusses evaluation methodologies used by Stone & Webster to determine the power benefits for six potential hydropower projects at existing U. S. Army Corps of Engineers...

Reliable Operation of Hydro-Thermal Power Systems
The demonstrated model allows planners to account for both operating and shortage costs, subject to a constraint on the system failure rate. In addition, the optimal long-term operation...

Pumped Storage and Power System Operations
The 2100 megawatt Bath County pumped storage power station began commercial operation in December 1985 as a jointly-owned project of Virginia Electric and Power Company (Virginia Power)...

Operational Flexibility?A Precious Commodity
This discussion is about Operational Flexibility, as it applies to the generating resources of a large electricity system. The author discusses the situation at Ontario Hydro, operationally...

Determination of Values of Project Storage for Hydropower Scheduling
The Columbia River is characterized by multiple and sometimes conflicting uses, and its basin extends over many political jurisdictions. To balance pluralistic needs and authorities with...

Marketing Power in the Pacific Northwest
The marketing of power in the Pacific Northwest is a process intimately tied to the management of the Columbia River system. This paper describes the characteristics of the river and transmission...

Columbia River Treaty Perspectives
The Columbia River Treaty was signed in 1961 and ratified by the governments of Canada and the United States in 1964. The Treaty required British Columbia to construct three large storage...

Reservoir Regulation in the Monsoon Climate of Korea
An examination of reservoir regulation rules in light of uncertain estimates of river flow in the Han River Basin, Republic of Korea, shows that two strategies will improve total hydroelectric...

Multisite Hydrocomplex Optimization
A multisite complex is analysed in northern Quebec to decide the level of equipment needed that will supply firm energy at the best possible unitary price. Four possible sites were chosen...

Hydropower Development of China's Yangtze River
The Yangtze has eight times the hydro potential of the Columbia River basin, currently the largest developed hydro system in the world. In order to pursue economic development through...

Computer-Aided Operation of a Hydropower System
This paper outlines the development of a computer model which optimizes the operation of a regulated river system given certain constraints using an adaptive deterministic linear programming...

A Case Study of Hydropower Operation Based on Runoff Forecast
The intent of this paper is to outline a forecast approach developed to enable the operation of power storage projects, and to illustrate from employing the approach that overall system...

Hydrologic Dispatch Model for a Hydropower System
A hydrologic dispatch model was developed for an 11 plant, six reservoir hydroelectric system. The model incorporates load forecasting, system dispatching strategy, and database management...

Optimal Operation of the Savannah River System
This paper presents an application of a stochastic control method to the real time operation of the Savannah river system which includes three reservoirs and is expected to meet energy...

DURAPLOT: A Flexible Approach to Hydropower Site Optimization
The U. S. Army Corps of Engineers, North Pacific Division Office has over the past six years performed reconnaissance and feasibility level hydropower studies at a variety of sites throughout...

The Use of Time Series Analysis to Estimate Flow Duration Curves to Assess Energy Potential for Low Head Hydro Redevelopment
The proposed hydroelectric site location has a low head potential making discharge the primary energy production component. A flow duration curve (FDC) study was commenced to generate...

The Role of Headwater Benefits in Hydropower Planning
Headwater benefits are the power benefits that accure to owners of downstream hydroelectric plants as a result of the operation of headwater improvements. The retention of water in upstream...

Using Fall Streamflows as Predictors of Spring Runoff at the Dalles, Oregon
The Northwest hydropower system is characterized by a drawdown season when normally full reservoirs are drafted to meet firm obligated loads, and a refill season in which the reservoirs...

Dam Safety Emergency Action Plans?A TVA-State Responsibility
The Federal Guidelines for Dam Safety requires each dam owner to prepare and maintain emergency action plans (EAP) for each of structure. These plans are necessary (1) to identify problems...
