“…The approach analyzed herein allows all the functionalities reported above and indicated in Table 1, but it was exclusively presented in [6] and only restricted to the case of three-phase four-wire (i.e., 3φ-4w) networks. While operation with a neutral connection is of significant importance and gives full flexibility for output power control [10,[18][19][20], the case without a neutral connection is still of interest and can be commonly found in grid-tied applications [21][22][23]. For this latter case originally considered herein, the independent, phase-by-phase control of the output active and reactive power, which results in six variables in total, is not possible, and only a subset of the output powers can be controlled instead.…”

This manuscript describes the operation of a droop-based controller for three-phase converters in the case of the absence of a neutral connection to the grid. The controller is capable of output power tracking and smooth transitions into the islanded operation. While independent per-phase control of the converter output power is possible if a neutral connection is present, its absence implies additional constraints to be considered. Focusing on this latter case, the controller described herein allows the independent control of the active power at the output of each phase of the converter and a smooth transition to the islanded operation. These features are paramount in future smart power systems, such as smart microgrids, for implementing demand–response, power-flow management, and uninterrupted power operation.

“…In these circumstances, distributed energy sources and the integration of storage systems can play an important role in overcoming this problem [6]. Microgrids (MG) have been implemented worldwide with the main purpose of mitigating the negative impact on the environment, by facilitating the integration of distributed renewable energy generation [7,8]. MGs can supply remote areas as well, but they are constrained by the inclusion of a key component, namely the energy storage solutions [9].…”

As climate changes intensify the frequency of severe outages, the resilience of electricity supply systems becomes a major concern. In order to simultaneously combat the climate problems and ensure electricity supply in isolated areas, renewable energy sources (RES) have been widely implemented in recent years. However, without the use of energy storage, they show low reliability due to their intermittent output. Therefore, this article proposes a methodology to achieve the optimal sizing of an energy storage system (ESS) to ensure predefined periods of safe operation for an ensemble consisting of multiple loads, renewable energy sources and controllable generators, located in a remote microgrid. In this regard, a mixed integer linear programming (MILP) model has been proposed to reduce the outages impact of critical loads by calculating the optimal ESS capacity and defining the proper resources management within the off-grid microgrid, while ensuring a cost-effective operation of its components.
