Optimize Dispatchers of Cascade Hydropower Station Based on IS-NGA

2013 Third International Conference on Intelligent System Design and Engineering Applications, 2013
Because the short-time optimized dispatcher question has some characteristics such as high dimension, non-protruding, dispersed, non-linear etc., so need one algorithm with high calculation precise and convergence speed to solve this question. This paper put forward one improve self-adaptation niche genetic algorithm, its characteristic mainly is ...

Analysis on Electricity Pricing Mechanism for Cascade Hydropower Stations in China

Applied Mechanics and Materials, 2011
For the large cascaded hydropower stations, an electricity pricing mechanism of cascade hydropower stations on large basins is proposed. The main idea is that the electricity generated by different hydropower stations on the same river can be sold to the Grid Corporation with the same price.

Self-scheduling of cascaded hydropower stations based on Nonlinear Complementarity approach

2010 International Conference on Power System Technology, 2010
A self--scheduling model of cascaded hydropower stations in day-ahead energy market is established in the paper. The objective of the model is to maximize generation profit. The multi stage model is nonlinear and contains complex constraints. To solve such a model is a challenging task.

Optimal operation of cascade hydropower stations using hydrogen as storage medium

Applied Energy, 2015
The use of forecast information for cascade hydropower stations is one of the effective ways to increase the electricity generation reliability and economic benefit. However, the uncertainty of forecast is high when the forecast horizon is long. It is a common practice for hydropower stations to abandon water during flood seasons due to the limited ...

Application of Decision Support System to Three Gorges Cascade Hydropower Station

2008 Second International Conference on Genetic and Evolutionary Computing, 2008
Three Gorges (TG) cascade stations plays an important role in power system, which is a major power supply station burdened with trades between multi-provincial grids. Hydropower Scheduling Decision Support System (TGDSS) is developed to improve scientific and economy of reservoir operation.

Long-Term Risk Dispatching of Cascaded Hydropower Stations in Electricity Market

2009 Asia-Pacific Power and Energy Engineering Conference, 2009
In the first-stage of power market, hydroelectricity still participates in electricity market with long-term or short-term electricity contracts. So, there may be risk for hydroelectricity due to forecasted error of reservoir runoff or other uncertain factors.
