Abstract

This Special Issue of Energies, “Modern Power System Dynamics, Stability and Control”, addresses the core problem of deploying novel aspects in the analysis of modern power systems as these are composed after the high penetration of distributed generation (DG) with different renewable energy sources (RES). The focus is given either on the new whole power and control system configuration or on individual cases of DG sources, power converters and other general or specific plants and devices. The problem can be tackled with different methodologies and may have several, more or less valuable and complicated solutions. The twenty-three accepted papers certainly offer a good contribution in a wide range of applications; they are extended from basic system theory perspectives, fundamental nonlinear analysis tools and novel modeling deployments to some interesting particular system and control issues.

Highlights

Power systems are continuously changing to effectively incorporate distributed generation (DG)with high levels of penetration of different renewable energy sources (RES), such as wind turbine or photovoltaic (PV) systems
Power electronic converters play a key role in the system, operating as controlled power interface devices and allowing local control of both directions of power flow, typically at notable distances from the main grid
In the new structure of modern power systems, the RES dynamics and control, the DG and micro-grid operation and stability in islanding or grid-connected mode, are of great importance, whereas high-voltage direct current (HVDC) links are vital for balancing the power of the grid
