Storage selection for DG applications containing virtual synchronous generators

Abstract

The paper is presenting an algorithm for establishing the best types of electrical storages for the virtual synchronous generator (VSG), depending on the application case and desired nominal power of the VSG. The resulting application provides a description of available technologies in terms of characteristics matching the desired properties of the storage in accordance with the scenarios described by the user.

Notice of Violation of IEEE Publication Principles: LFC by coordinated virtual inertia mimicking and PEVs in power utility with MW-class distributed PV generation

“…Since the fundamental concept of VSMs was formally introduced, it has been subject of several publications. Most of the research deals with specific issues on the implementation of VSMs such as: the necessary requirements of the PEI to perform a VSM [3], selection of the storage media [4], laboratory prototypes for experimental tests [5] and an optimal virtual inertia controller for wind generator [6].…”

Again On The Constitutive Or Transferring Effect Of Property-Related Rights Of The Registration With The Land Book

“…Practically, within the same legal operation, two different manners in which the transfer of propertyrelated rights in rem is operated are recognized: solo consensu in the relations between the parties and as of the registration date, in the relations with the third parties, creating the conditions for the occurrence of equivocal and pernicious legal situations [7] and definitely affecting the security of the civil circuit. This legal paradox: the occurrence of an (absolute) right in rem non-opposable to third parties [8] denunciated by the doctrine seems not to have left the law-maker totally indifferent since, on a more rigorous analysis of the provisions of Law no. 7/1996, in the form acquired after the amendments operated by Law no.…”

Research on Improved VSG Control Algorithm Based on Capacity-Limited Energy Storage System

“…In current study, DG and storage devices are commonly simplified as DC power sources. In [23,24], conclusions can be drawn that it is the charge and discharge progress of the storage devices that form the virtual inertia. In [25], an optimal control strategy of the storage systems by setting the VSG's output active power depending on the grid frequency deviation is put forward.…”
