Jay R. Lund, Professor Department of Civil and Environmental Engineering University of California, Davis Davis, CA 95616 [email protected] ABSTRACT Theoretical hydropower operation rules are derived and discussed for reservoirs in parallel, in series, and single reservoirs for cases where reservoirs typically refill before they empty and for parallel reservoirs when reservoirs are expected to ...

We study dynamic duopolistic competition between hydro and thermal generators under demand uncertainty. Producers compete in quantities and each is constrained: the thermal generator by capacity and the hydro generator by water availability. Two versions of the model are analysed: an infinite-horizon game emphasizing water withholding incentives of the hydro generator and the distribution of pr...

Demand for hydropower is increasing, yet the water footprints (WFs) of reservoirs and hydropower, and their contributions to water scarcity, are poorly understood. Here, we calculate reservoir WFs (freshwater that evaporates from reservoirs) and hydropower WFs (the WF of hydroelectricity) in China based on data from 875 representative reservoirs (209 with power plants). In 2010, the reservoir W...

Abstract: At present, the common practice in the power system of China is to represent the small and medium hydropower generator group as a negative load. This paper presents a method to build a dynamic equivalent model of the hydropower generator group using a 3rd order generator model and a static characteristic load model. Based on phasor measurements in the tie line which connects to the mo...

Standard operating policy and hedging policies are commonly used for reservoir operation for municipal or irrigation water supply. Application of these policies to hydropower reservoir operation is complex. In this paper, new standard operating policies and standard hedging policy are proposed for hydropower reservoir operation. The newly proposed policies were applied to the operation of Indir...

ABSTRACTRenewable Energy Sources (RES) are well – defined as energy sources, that are in abundance within the natural surroundings and are much inexhaustible. In addition, hydroelectricity (HE) is a vital part of world renewable energy supply and hydropower remains a bulk source of electricity generation because of its environmental friendliness in nature. Modeling is the analysis of the ...

In an earlier paper (Kosnik, 2008), the potential for small scale hydropower to contribute to US renewable energy supplies, as well as reduce current carbon emissions, was investigated. It was discovered that thousands of viable sites capable of producing significant amounts of hydroelectric power were available throughout the United States. The primary objective of this paper is to determine t...
