In this paper, a new approach is considered for relay aided smart meter to smart meter communication in a microgrid. In the considered framework, a group of smart meters (SMs) simultaneously exchange pricing data with each other for selling or purchasing energy. At the same time, another group of SMs forward load demand and generation information to the control centre as these are the most important...
In this paper, we design an architecture of Energy Management Systems (EMS) for resilient operation of microgrids and describe autonomous mechanisms that dynamically enable 1) enhancement for scalability, 2) system modification and upgrade, and 3) failure detection and recovery. Designing the resilient architecture and achieving autonomous mechanisms are of critical importance for a system operator...
As more distributed energy resources (DERs) such as PV generation, batteries and electrical vehicles are installed in the distribution grid, controlling the voltage to be within allowed limits is becoming a major challenge. A possible solution is to actively use the active and reactive power control capabilities of these DERs to keep the voltage within limits. For this purpose, new control algorithms...
Microgrids offer a flexible, modular, and scalable solution to facilitate the adoption of renewable energy sources, e.g., solar power, in distribution networks. Noticeably, the cost of daily operation of a microgrid is tightly coupled with its long-term planning decisions, such as the placement of renewable energy sources. This paper studies the optimal placement of solar panels in a grid-connected...
In this paper, we propose a game theoretic modelling paradigm for the energy trading market of a Microgrid Social Network (MGSN) architecture in which the networked Microgrids (MGs) are connected by a common physical bus and social networks. In the considered MGSN, individual MGs involved in energy trading, called market participants, make decision on energy trading based on the state estimation of...
The development of smart grid, electric vehicles (EV), and integration of renewable energy sources (RES) changes the existing power grid. Volt-VAR optimization (VVO) is a well-known problem to reduce the losses along the distribution lines. Current VVO does not endorse the role of elastic and inelastic loads, EVs, and RESs to decrease the reactive losses and hence the cost of generation. We propose...
We analyze the benefit of storage capacity sharing for a set of consumers in a community (e.g., an apartment building or an industrial park). Each consumer has its own choice of either installing its own storage system or investing in a shared storage system. More precisely, they will decide on the capacity of the storage system to minimize the installation cost subject to a chance constraint for...
Microgrid protection schemes are different from those used in conventional distribution networks. With the incorporation of distributed generation (DG), and the ability for bi-directional power flow and island operation; the fault current and delay parameters of protective relays need to be recalculated and updated in response to the dynamic operation of microgrid. Performance evaluation (e.g. fault...
