TLDR
The hierarchical control derived from ISA-95 and electrical dispatching standards to endow smartness and flexibility to MGs is presented and results are provided to show the feasibility of the proposed approach.Abstract:
DC and AC Microgrids are key elements to integrate renewable and distributed energy resources as well as distributed energy storage systems. In the last years, efforts toward the standardization of these Microgrids have been made. In this sense, this paper present the hierarchical control derived from ISA-95 and electrical dispatching standards to endow smartness and flexibility to microgrids. The hierarchical control proposed consist of three levels: i) the primary control is based on the droop method, including an output impedance virtual loop; ii) the secondary control allows restoring the deviations produced by the primary control; and iii) the tertiary control manage the power flow between the microgrid and the external electrical distribution system. Results from a hierarchical-controlled microgrid are provided to show the feasibility of the proposed approach.read more

Socio-economic acceptability for smart grid development – a comprehensive review
TL;DR: In this paper, a literature review of 148 peer-reviewed scientific journal articles on smart grids has been conducted, developing an original taxonomy for the socioeconomic features in terms of private (direct) costs directly associated with the monetary costs paid by consumers and social (indirect) costs constituted by consumers' perception, privacy, cyber security and regulation.

The path of the smart grid
TL;DR: The electrical power industry is undergoing rapid change as discussed by the authors, and the major drivers that will determine the speed at which such transformations will occur will be the rising cost of energy, the mass electrification of everyday life, and climate change.

Control of parallel connected inverters in stand-alone AC supply systems
TL;DR: In this article, a control scheme for parallel-connected inverters in a standalone AC supply system is presented, which uses feedback of only those variables that can be measured locally at the inverter and does not need communication of control signals between the inverters.

Output impedance design of parallel-connected UPS inverters with wireless load-sharing control
TL;DR: This paper deals with the design of the output impedance of uninterruptible power system (UPS) inverters with parallel-connection capability, and proposes novel control loops to achieve both stable output impedance and proper power balance.
