Modeling Smart Grid Applications with Co-Simulation

Abstract: Our analysis of a complex Smart Grid control scheme uses simulation to model both the communication network and the power system. The control scheme uses a wireless communication network to activate distributed storage units in a segment of the electrical grid to compensate for temporary loss of power from a solar photovoltaic (PV) array. Our analytical model of the communication network provides a means to examine the effect of communication failures as a function of the radio frequency (RF) transmission power level. We use these results in an open source event-driven simulator to determine the impact on the electrical power system.

Imagining energy futures: Sociotechnical imaginaries of the future Smart Grid in Norway

Abstract: A future “Smart Grid” is increasingly being embraced in energy policies as a promising energy scenario for the future, with the introduction of “smart” electricity meters being seen as the first step In Norway, this process is happening without much public debate Discussions of complexity and uncertainty related to the future Smart Grid are mainly taking place within a network of actors with recognized expertise Based on empirical data from interviews and documentary analysis, this paper describes sociotechnical energy imaginaries of a future Smart Grid in a Norwegian context from within this network of experts, which is conceptualized as a techno-epistemic network The future imaginaries of smart meters and a future Smart Grid are mainly technological and economical, and they are partly permeated by national imaginations They connect the past and the future by providing solutions for current challenges in the energy supply system, which reflect current institutional and technological structures The imaginaries also include constructions of the public, or “consumers”, which has implications for the communication to the public The paper suggests that increased openness and the inclusion of multiple perspectives and ways of knowing, inspired by post-normal science, could facilitate more careful consideration of potential social implications

Optimal ESS Allocation for Load Management Application

Abstract: The recent deployment of distributed generation has led to a revolution in the use of distribution systems and the emergence of “smart grid” concepts. Smart grids are intended primarily as a means of facilitating the integration of renewable energy sources and of achieving greater system reliability and efficiency. Energy storage systems (ESSs) offer a number of benefits that can help utilities move toward those goals. One of those benefits is the capacity to improve the utilization of network infrastructure by means of proper load management. This paper proposes a methodology for allocating ESSs in distribution systems in order to defer system upgrades, minimize system losses, and take advantage of the arbitrage benefit. The cost and arbitrage benefit of energy storage installation are optimized with respect to system upgrade and energy losses costs. The primary goal of this research is to determine the optimal size and location of storage units to be installed, in addition to their optimal operation, so that total system costs are minimized, while system benefits are maximized. In this paper, a probabilistic load model is adopted instead of utilizing time-series based models, which provide an optimal solution that is valid only for the time-series pattern that is applied.
