A computer model was developed at Oak Ridge National Laboratory to analyze the electricity production, costs, and prices for two geographical regions for a single year. Bulk-power trading is allowed between the two regions and market clearing prices are determined based on marginal costs. The...

We provide some basic background information on support for renewable in California on the expected operation of the power pool and bilateral markets, and on the three key policy types modeled here. We discuss the Elfin production cost and expansion planning model as well as key assumptions that...

Human and earth systems are extremely complex processes. The modeling of these systems to assess the effects of climate change is an activity fraught with uncertainty. System models typically involve the linking of a series of computer codes, each of which is a detailed model of some physical or...

Operational systems predict the consequences of atmospheric releases of hazardous materials for real-time emergency response, pre-event planning, and post-incident assessment. Such systems provide federal, state, and local agencies, emergency planners and responders, public health officials,...

This paper deals with the market for SO{sub 2} emission allowances over time and electric utility compliance choices. For currently high emitting plants ( 2.5 lb SO{sub 2}/MMBtu), the 1990 Clean Air Act Amendments (CAAA) provide for about twice as many SO{sub 2} allowances to be issued per year...

A previous report explored and discussed statistical methods and procedures that may be applied to validate the survivability of a complex system of systems that cannot be tested as an entity. It described a methodology where Monte Carlo simulation was used to develop the system survivability...

The purpose of this paper is to document the results of our application of the Edmonds-Reilly Model (ERM) using several scenarios provided for an Organization for Economic Cooperation and Development (OECD) project comparing global models. Because the output of this exercise is data-rich, most...

This paper describes an approach that was developed to produce structured models that graphically reflect the requirements contained within a text document. The document used in this research is a draft policy document governing business in a research and development environment. In this paper,...

Accurate forecasts of officer retention rates are required in order to shape correctly the size and internal structure of the Navy manpower force through accession, promotion, and related policies. This study, conducted in 1987 for the Navy Personnel Research and Development Center (NPRDC),...

In recent years, modeling and simulation has played an increasingly important role in the maintenance of the nuclear stockpile. The Advanced Simulation and Computing (ASC) program continues to support and encourage the development of a modeling and simulation infrastructure to make these goals a...
