The paper presents an automatic power management system (PMS) designed for the on-line operation of an experimental low voltage microgrid equipped with two power supplies, a kW-class fuel cell (FC) and a photovoltaic (PV) module emulator, along with a 100-Ah battery storage system, all connected to a 230 VAC node. The connections of the various components to the common AC bus make use of power ...

In this paper I propose a tweakable block cipher construction with a mode of operation that combines counter and chaining methods. Using a single key, the direct application of this mode produces unrepeatable message authentication tags.

Controlling voltage, frequency, and current in an islanded microgrid is a challenging problem because the distributed generation sources, stochastic intermittent nature, are not connected to main electricity network provide stable clean energy. Therefore, design of robust controller control output parameters suppress load variations disturbances essential. In this paper, hysteresis proposed des...

The present scenario is towards shifting centralised power generation (central grid) to distributed generation (micro grid) with smaller sources of capacity. The isolated micro grid is connected to main grid with inverters at the front end for efficient exchange of power sharing; power exchange among distributed generation (DG) sources in an isolated micro grid is possible with droop characteri...

his investigation tried to control a standalone hybrid DC microgrid in islanded operation mode by using decentralized power management strategies. Unlike common approaches where a Photovoltaic (PV) module is controlled as current source, the proposed strategy controls PV arrays as a voltage source that follows the current/voltage adaptive characteristic curve. Proposed I/V characteristic for hy...

Complex circuitry of electronic infrastructure of compact micro-grids with multiple renewable energy sources feeding the loads using parallel operation of inverters acts as a deterrent in developing such systems. This paper deals with applicable techniques reducing the driving circuits in parallel power inverters used in micro-grid system (MGS), mainly focused on the distributed generation (DG)...

A zero-inertia micro-grid is a power system consisting of multiple renewable energy sources and storage systems without the presence conventional synchronous generators. In such system, large variation load or source sides during islanded mode operation extremely degrades micro-grid's voltage frequency stability. This study presents virtual inertia-based predictive control strategy for small-sc...

This article proposes a novel synchrophasor-based control scheme enabling controlled islanding, islanded operation and automatic re-synchronization of distributed energy resource (DER) in distribution network. The performance the proposed system is studied using test power model. DER controller uses centralized architecture, receiving phasor measurement unit (PMU) measurements from both transmi...

In this article, a cyber-resilient consensus-based distributed control scheme is proposed for islanded ac microgrids.
