Derivation of Monthly Operating Rules for Cascade Hydropower Stations Based on SVM

Advanced Materials Research, 2013
In order to promote the efficiency of actual hydropower system operation under limited inflow forecast, an Implicit Stochastic Optimization method using Support Vector Machine (SVM) theory is proposed in this paper to derive long-term optimal operating rules.

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 ...

Short term hydropower dispatching optimization of cascaded hydropower stations based on two-stage optimization

2010 2nd International Conference on Industrial and Information Systems, 2010
A two-stage optimization strategy and its models for short-term hydropower dispatching optimization is developed to solve unit commitment and load distribution problem with unit commitment optimization sub-model and min water consumption sub-model. Moreover, improved ant algorithm with new selection mechanism and iteration mechanism are introduced for ...

Optimization Scheduling of Cascade Hydropower Stations in Energy Conservation and Emission Reduction

Advanced Materials Research, 2013
Considerable water saving and electricity can be attained by optimal regulation of cascade hydropower plants, equivalent to building large and medium-sized hydropower stations without increase in investment and immigration. Thus, the optimal regulation of cascade hydropower plants has great significance on increasing the consumption ratio of fossil ...
