In this paper, a much more detailed representation of the nation's electricity system than has been traditionally used in policy models is employed. This detailed representation greatly increases the computational difficulty of obtaining optimal solutions, but is necessary to accurately model the location of new investment in generation. Given the proposed regulation of CO2 emissions from US power...
In this article, we demonstrate that how closing the loop between operational dynamics and investment decisions for microgrids allows us to explicitly incorporate short-term operational volatility and long-term financing and market variations into investment decisions. Here, microgrid cost savings function describing the short-term benefit growth of the micro-grid under short-term (operational) uncertainties...
With an increasing number of small-scale renewable generator installations, distribution network planners are faced with new technical challenges (intermittent load flows, network imbalances…). Then again, these decentralized generators (DGs) present opportunities regarding savings on network infrastructure if installed at strategic locations. How can we consider both of these aspects when building...
The growing environmental concerns and increasing electricity prices have led to wider implementation of demand-side activities and created a new class of consumers, called demand response resources (DRRs). The DRRs actively participate in the electricity markets as buyers of electricity and sellers of load curtailment services. The demand profile modifications resulting from the DRR curtailments...
This paper presents a comprehensive modeling approach that addresses the long-term generation expansion planning problem for an investor firm operating in a deregulated market environment. The mathematical model facilitates the ability of multi-period investments in multi-technology generation options. This work provides insight into the nature of the planning problem by determining optimal timing...
The ambiance in virtual environments is affected by the loss of multimodal information. For many purposes, the affective qualities of a virtual environment require special attention in the modeling process. In order to construct the right ambiance it can be beneficial to engineer the affective appraisal of the virtual environment. However, a userpsilas assessment of the affective qualities of a (virtual)...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
The paper discusses the study to develop a new financial evaluation framework for power transmission expansion projects in South Africa (SA) that can also be suitable for handling change and uncertainty in the electricity supply industry. The research design followed in the study is model building, testing and application empirical research. The development of the new financial evaluation framework...
A critical infrastructure (CI) consists of those physical and information technology facilities, networks, services and assets which, if disrupted or destroyed, have a serious impact on the health, safety, security or economic well-being of citizens or the effective functioning of governments. Nowadays, the operation controls of these infrastructures have been computerized and have gradually become...
