This article proposes a modular control design for Dynamic Virtual Power Plants (DVPPs) that enables the flexible and scalable integration of heterogeneous Distributed Energy Resources (DERs) to provide grid-forming capabilities for modern power grids.
Statystyki
The desired dynamic response includes an inertia time constant of 5 seconds.
The desired frequency droop sloop is 1/25, equivalent to 4%.
The desired voltage droop sloop is 20%.
The AC-DC matching relationship aims for a 10% DC voltage-square variation for a 1% frequency variation.
The DVPP in the case study consists of a supercapacitor, a battery energy storage system, and a photovoltaic system with power setpoints of 0.0, 0.0, and 0.5 pu, respectively.
The power limitations for the supercapacitor, battery, and photovoltaic system are 0.3, 0.3, and 0.7 pu, respectively.
Cytaty
"DVPPs are distinguished by their focus on the collective response to fulfill a desired response to the output-terminal grid, as opposed to the localized operation of individual DERs in a microgrid."
"A modular DVPP introduces a flexible and scalable approach to building AC/DC hybrid power grids."
"The dynamic and steady-state participation can be adapted by tuning the time constant and static gain in mi(s)."
