Cover Story: A method for operating AC microgrid in both off-grid or standalone and grid-connected modes is proposed here to minimize the use of energy storage by having more PV panels and taking curtailment of their output power. When the sunshine becomes dim, planned power import from the main grid or a local large-microgrid through AC-AC converters is conducted to compensate the shortage. The whole AC microgrid is operated at constant frequency with necessary reactive power compensation. Therefore power qualities of both voltage and frequency can be ensured. View this paper.

Electrochemical Synthesis of Germanium-Polypyrrole Composite Nanomaterials in Ionic Liquids for the Fabrication of Lithium-Ion Batteries

Received: 26 December 2021;  Published: 27 March 2022;  doi: 10.21926/jept.2201010

Abstract

Herein, we report the coating of nanostructured germanium using a polypyrrole (PPy) polymer coat as a composite anode material for the fabrication of lithium-ion batteries. The Ge/PPy composites were synthesized following the direct electrochemical deposition method in an ionic liquid (IL). The resu [...]

Operation of AC Microgrids with PV Panels’ Output Power Curtailment for Minimizing the Use of Energy Storage

Received: 21 January 2022;  Published: 07 March 2022;  doi: 10.21926/jept.2201008

Abstract

In this paper, a method for operating AC microgrids in both off-grid or standalone and grid-connected modes is proposed to minimize the use of energy storage by increasing the number of PV panels and curtailing their output power. When the intensity of daylight decreases, power is imported from the [...]
