RISShort-Term Scheduling for Large-Scale Cascaded Hydropower Systems with Multivibration Zones of High Head
Publisher: American Society of Civil Engineers
Abstract: Construction of huge hydropower plants in the southern region of China has been rapidly increasing in recent years. These plants usually have multiple vibration zones of high head that have a great effect on short-term ...
Long-Term Optimization of Large-Scale Hydropower System Operations Based on Decomposition-Coordination
Publisher: ASCE
Abstract: The basic objective of long-term optimization of large-scale hydropower system operations (LOLHSO) is to increase water resource use efficiency and construct a clean and low-carbon-intensity energy system. However, limited ...
Multiobjective Scheduling Method for Short-Term Peak Shaving Operation of Cascade Hydro Plants
Publisher: ASCE
Abstract: With structural changes in power consumption, peak load demands and peak-valley differences are growing, which motivates peak shaving operations of hydropower systems. A multiobjective mixed-integer nonlinear programming ...
A Short-Term Hydropower Scheduling Model Considering Constraint Priorities
Publisher: ASCE
Abstract: Models for short-term optimal scheduling of hydropower stations should consider complex cascade constraints, hydropower station constraints, and unit operation constraints, all of which are inextricably linked. In practical ...
Multicore Parallel Genetic Algorithm with Tabu Strategy for Rainfall-Runoff Model Calibration
Publisher: American Society of Civil Engineers
Abstract: Conceptual rainfall-runoff models (CRRMs) are widely used for flood forecasting and hydrologic simulations. However, parameter calibration poses a major challenge for using CRRMs, especially given that climate changes and ...
Power Generation Scheduling for Integrated Large and Small Hydropower Plant Systems in Southwest China
Publisher: American Society of Civil Engineers
Abstract: Electric power transmission lines in service in southwest China have fallen far behind the power sources. With rapid development of hydropower in this area, severe water spills for hydropower frequently occur during the ...

Centralized versus Distributed Cooperative Operating Rules for Multiple Cascaded Hydropower Reservoirs
Publisher: American Society of Civil Engineers
Abstract: Multiple cascaded hydropower reservoir systems serving the same area need to cooperate to increase overall benefits and reliability. To meet system demand while balancing among cascaded systems, both centralized and ...
Long-Term Market Competition Analysis for Hydropower Stations using SSDP-Games
Publisher: ASCE
Abstract: With the development of the power market in China, the operation of hydropower stations will be changed significantly. In a competitive environment, each hydropower station or station group tries to improve its own net ...
Optimal Hedging for Hydropower Operation and End-of-Year Carryover Storage Values
Publisher: American Society of Civil Engineers
Abstract: Hedging rules for hydropower operation provide optimal decisions to hedge against extreme system loss from an energy shortfall in the future at the price of a small current loss. Aiming at determining optimal end-of-year ...
