A key issue in LV distribution system management and control is to increase the flexibility of the existing networks so as to allow a large spread of Distributed Energy Resources (DERs). In this perspective, virtual levels of aggregation, called Virtual Microgrids (VMs), are introduced, which are composed of parts of the distribution networks including different types of DERs and their control systems...
A large penetration of Distributed Generation (DG) may severely impact on the voltage profiles along LV distribution feeders. The first, cheapest and simplest step that can be undertaken is to involve DG units in the voltage control of the LV distribution networks, adopting a fully-decentralized architecture and avoiding any additional communication infrastructure. The paper proposes a design methodology...
Distributed energy resources, such as distributed generators and storage systems, are generally considered as active power sources. Indeed, they can also be used as reactive power resources, which contribute to reduce the power losses in a distribution feeder. Adopting a decentralized approach, in this paper an on-line Optimization Strategy is introduced to define the optimal set point of a classical...
