Application of Dual-Grid-Forming MMC for Seamless Transition between Grid Connected and Islanded Operation in Microgrids

This paper presents a control strategy based on dual-grid-forming applied to modular multilevel converters. The goal is to ensure seamless transitions between grid-connected and island operations in ac microgrids. This control strategy is tested in a case where a back-to-back multilevel converter...

A Platform for Development and Testing of WAMPAC Applications based on Kafka Streaming

In this paper a platform for developing and testing Wide Area Monitoring, Protection and Control (WAMPAC) applications is presented. The fundamental idea is that individual applications operate as microservices. Each application access and process data (e.g. data from Phasor Measurement Units) and...

An Improved Dual Grid-Forming MMC with Port-Hamiltonian Structure

The operation of converters interconnecting ac and dc grids in future inertia-free and weak networks poses significant challenges. Modular multilevel converters applying dual grid-forming controls are able to effectively synchronize to weak grids and control the dc voltage levels simultaneously...
