Virtual synchronous machines (VSMs) have been widely investigated for improving the
inertia of power systems and providing reliable frequency control against rapid penetration …

The proliferation of renewable energy sources in autonomous microgrids has led to the
deterioration of system inertia. In the past decade, the decrease in system inertia was …

In this study, analysis of a high-efficiency grid-connected pump hydro energy storage
(PHES) system that uses a bidirectional brushless DC (BLDC) machine is presented. The …

Modern grids contain new components, such as renewable power resources, HVDC
transmissions, energy storage systems and others. These new components will affect the …

Pump hydro energy storage (PHES) is vital for grid stability. The traditional system lacks
flexibility, so variable-speed machines are gaining attention. The study focuses on a variable …

Direct-drive permanent magnet wind turbine has high power generation efficiency,
especially in low wind speed environment, and is widely used for wind power generation …

Mediante esta tesis se desarrolla un método de control en cascada para la integración de
generación distribuida a redes eléctricas, cuya tensión se encuentra desequilibrada. Estas …

A multi-objective control for grid interfaced PV-BES based pico hydro system having multi
mode operation is dealt in this work. The pico hydro system comprises of a PMSG driven by …

In order to deal with the stability and security problems of power system operation brought
by large-scale new energy grid connection, this paper proposes a modular multilevel energy …
