The current power system suffers from inherent inefficiencies and transmission line congestion due to the spatial split between power generation and end usage. This potentially introduces shortcomings in meeting load demands, grid liability, renewable portfolio standards, and environmental considerations such as carbon emission reduction targets. The economic and technical viability of distributed energy resource (DER) technologies may accelerate the transition to more sustainable energy production. This paper investigates the economic and environmental benefits of DERs compared to utility prices and emissions for residential dwellings using the Distributed Energy Resources Customer Adoption Model (DER-CAM). The results show a tradeoff between the CO2 emissions and electricity costs, but improvements over purchasing the electricity.

Distributed energy resource integration in power systems has advantages and challenges in both the economic and the technical operation of the system. An aggregator, as in the case of a Virtual Power Player, is essential in order to support the operation of these small size resources. Innovative approaches capable of supporting the decisions made in terms of resource scheduling, aggregation and remuneration are needed. The present paper addresses a methodology capable of managing resources through the activities of an aggregator, providing different choices of aggregation and remuneration strategies. The methodology is validated in a case study regarding a 21-bus network, composed of 20 consumers and 26 producers.

Distributed Energy Resource

Electricity has traditionally been a commodity that is bought and sold through a rigid marketplace between an electric utility and a ratepayer. Today, however, the electricity market is rapidly evolving to be comprised of distributed energy resources and microgrids that change the structure of the technical and financial relationship between utilities and ratepayers. Regulation, a reduction in cost of renewable energy technologies, interoperability and improved communications, and public interest in green power are facilitating this transition. Microgrids require an additional layer of control, often use preprogrammed rule sets, and lack bi-directional self-awareness, self-management, and self-diagnostics necessary to dynamically adapt to changes on-site and in the grid. Research is needed in optimization and controls. This study explores the viability of self-organizing control algorithms to manage multiple distributed energy resources within a distribution network and reduce electricity cost to one or more ratepayers having such resources installed on-site. Such research provides insight into the transition from a traditional power distribution architecture into a flexible smart network that is better prepared for future technological advances, renewables integration, and customer-side control. Agent-based techniques are employed for least-cost optimization and implements these to manage transactions between three decentralized distributed energy resource systems within an electrical network.

Abstract The decreasing cost of implementation and increasing regulatory incentive to lower energy use have led to an increased adoption of distributed energy resources in recent years. This increased adoption has been further fueled by a surge in energy consciousness and the expansion of energy-saving products and technologies. To lower reliance on the electrical grid and fully realize the benefits of distributed energy resources, many consumers have also elected to use battery systems to store generated energy. For owners of multiple buildings, or multiple owners willing to share the operational cost, building clusters may be formed to more effectively take advantage of these distributed resources and storage systems. The implementation of these systems in existing buildings introduces the question of what makes a “good” building cluster. Furthermore, the scalable nature of distributed energy sources and storage systems create countless possibilities for system configuration. Through comparison of unique two-building clusters from a stock of five buildings with a given distributed energy resource (in this case, a solar photovoltaic panel array) and energy storage system, we develop a fundamental understanding of the underlying factors that allow building clusters to be less reliant on the utility grid and make better use of energy generation and storage systems.

Abstract This paper presents the design, implementation and test of hardware in the loop simulation architecture for integration of Smart Buildings and distributed energy resources in Micro Grids. The rationale for this work is the integration of off-the-shelves devices in a HIL simulation setup within software development. The architecture and preliminary results are presented, together with a case study for integrating flexible units, such as a space heating system and Electric Vehicles in a Smart Building equipped with local solar energy production.

With emerging concerns over climate change and the need for reduced greenhouse gas emissions, together with the growing awareness of the importance of the natural environment and the depletion of the earth's non-renewable energy resources, the generation of electricity from distributed renewable energy resource such as solar photovoltaic (PV) and wind energy has begun to expand at a rapid pace. Proliferation of convert-based distributed energy resources in distribution systems has introduced new challenges in determining the maximum possible fault currents that a power system must be able to withstand without being compromised. Therefore is is imperative to develop the mathematical and software simulation models that approximate the response of converter-based distributed energy resources during a fault on the transmission or distribution system in order to determine the fault current contributions to the electrical grid that a transmission or distribution utility needs to reflect in their connection impact assessments.

Background/Objectives: The power demand of utility electrical power has stimulated the use of distributed energy for peak shaving. Distributed energy resources need to be monitored and controlled like Internet of Things.Methods/Statistical analysis: Distributed Energy Resources (DERs) are small scale electric energy system like Micro Turbine, Photovoltaic, Wind power, Small Generator and widely spread in Korea. For utilizing electrical device with Internet of Things, we need integrated system and adapt International Electrical Code like IEC 61850.Findings: To connect DERs with uninterrupted grid system, it required Closed Transition Transfer Switch (CTTS). Existing International Electrical Code presented some distributed energy resource by IEC 61850-7-420. However, the switch like CTTS is not presented. So, we described modeling of CTTS in IEC 61850 and verified monitoring data with TCP/IP.Improvements/Applications: The proposed modeling of CTTS not only combines the DERs with grid system but also conjugates smart grid system with IOT Technology.
