Microgrid power management scheme analysis: With the increasing use of renewable energy resources and energy storage devices, inverter-based distributed energy resources (DERs) become the important components in microgrids. As diesel generators with direct ac connections are the current most cost effective and reliable power sources, the stability investigation of microgrids should include both...

The integration of Distributed Energy Resources (DER) in the distribution network has plenty of advantages if their allocation and Penetration Level (PL) are done appropriately. Hence, the challenge of finding the best allocation and PL of DERs in large distribution networks is an important but intricate problem. This paper proposes a novel methodology to simultaneously determine the optimal lo...

The integration of large amounts of distributed energy resources (DERs) as photovoltaic solar generation, micro-cogeneration, electric vehicles, distributed storage or demand response pose new challenges and opportunities on the power sector. In this paper, we review the current trends on: i) how consumers adopting DERs can self-provide energy services and provide other services at system level...

With global conventional energy depletion, as well as environmental pollution, utilizing renewable energy for power supply is the only way for human beings to survive. Currently, distributed generation incorporated into a distribution network has become the new trend, with the advantages of controllability, flexibility and tremendous potential. However, the fluctuation of distributed energy res...

Until now the main purpose of Distributed Energy Resources (DERs) has been to compliment the power plants. However, if DERs are to play a larger role in the power grid of the future, then improved communication and cooperation between these resources and the system operators is necessary. Cooperation requires intelligence at the level of the DER as well as at the aggregator level, and in order ...

Coordinated optimization and control of distribution-level assets can enable a reliable and optimal integration of massive amount of distributed energy resources (DERs) and facilitate distribution system management (DSM). Accordingly, the objective is to coordinate the power injection at the DERs to maintain certain quantities across the network, e.g., voltage magnitude, line flows, or line los...

Classic unit commitment (UC) is an important and exciting task of distributing generated power among the committed units subject to several constraints over a scheduled time horizon to obtain the minimum generation cost. Large integration of distributed energy resources (DERs) in modern power system makes generation planning more complex. This paper presents the individual and collective impact...

This paper presents a microgrid planning model for determining the optimal size and the generation mix of distributed energy resources (DERs) as well as the microgrid type, i.e., AC or DC. Considering the growing ratio of DC loads and DERs, DC microgrids could be potentially more beneficial than AC microgrids by avoiding the need to synchronize generators, reducing the use of converters, facili...

This paper proposes a distributed algorithm for online energy management in networked microgrids with a high penetration of distributed energy resources (DERs). The implementation of networked microgrids with high penetration of DERs brings power generation closer to electricity users, which has advantages of increasing power supply efficiency and reliability by shortening the power supply deli...

Recent years have seen an unprecedented increase in the adoption of distributed energy resources (DERs) in distribution networks around the world. In most jurisdictions the increase in DERs has been met with a "fit and forget" network management approach whereby grid planners accommodate these resources by expanding the capacity of the network with conventional technologies. However, the contin...
