The FREEDM microgrid is a test bed for a smart grid integrated with Distributed Grid Intelligence (DGI) to efficiently manage the distribution and storage of renewable energy. Within the FREEDM system, DGI applies distributed algorithms in a unique way to achieve economically feasible utilization and storage of alternative energy sources in a distributed fashion. The FREEDM microgrid consists of residential...
WattDepot is an open source, Internet-based, service-oriented framework for collection, storage, analysis, and visualization of energy data. WattDepot differs from other energy management solutions in one or more of the following ways: it is not tied to any specific metering technology; it provides high-level support for meter aggregation and data interpolation; it supports carbon intensity analysis;...
In this paper, we outline the Grid 2.0 Research, a collaborative Smart Grid research program between Gachon Energy Research Institute (GERI) of Kyungwon University and Bell Labs of Alcatel-Lucent. Salient features of the Grid 2.0 Research are the active role of distributed fixed and mobile energy storage, distributed renewable energy sources, and active load-side participation. Our focus is not on...
Concerns about climate change and greenhouse gas (GHG) emissions would make us reduce our dependency on carbon-based energy sources. The current infrastructure is optimized for the use of carbon-based energy. Due to the low energy densities of low-carbon sources, the same infrastructure might not be suitable or efficient. Therefore, design issues pertaining to the low-carbon infrastructure are investigated,...
The paper proposes a mechanism for real-time pricing of electricity in smart power grids, with price stability as the primary concern. In previous publications the authors argued that relaying the real-time wholesale market prices to the end consumers creates a closed loop feedback system which could be unstable or lack robustness, leading to extreme price volatility. In this paper, a mathematical...
Recognizing the value of an advanced metering infrastructure (AMI), utilities worldwide are deploying millions of smart meters. To better justify AMI investment, researchers have recognized the urgency to utilize the full potential of AMI to improve the quality of distribution management system (DMS) applications. However, the integration of AMI and DMS is a challenge as it entails different communication...
Universal, intelligent and multifunctional devices controlling power distribution and measurement will become the enabling technology of the ICT-driven SmartGrid. In this paper we discuss a design and simulation environment which provides a virtual model of such devices and at the same time enables their interoperability and configurability. The solution is based on the combination of IEC 61850 interoperable...
