Originally, ancillary services (ASs) were provided by large-scale power plants to ensure the
secure and reliable operation of power systems. However, with the advent of renewable …

Traditionally, a grid-interactive inverter providing ancillary services is called a smart inverter.
However, broader features will be required for the next generation of inverters that can be …

The increasing penetration of renewable energy resources imposes challenges to the
distribution system operators to maintain the voltage levels and voltage unbalance within …

大力推动可再生能源发展是应对当前能源危机和环境问题的重要手段, 全球许多国家和地区陆续
提出未来向100% 可再生能源电力系统(100% renewable energy power systems, 100 …

In this paper, a centralized control strategy for low-voltage networks is proposed, aiming to
coordinate the droop characteristics of the distributed renewable energy sources. The main …

Proliferation of grid-connected photovoltaic systems (PVSs) causes technical problems due
to their variable and non-dispatchable generated power. High penetration of PVS in …

In Belgium, and many other countries, rooftop solar panels are becoming a ubiquitous form
of decentralised energy production. The increasing share of these distributed installations …

The increased penetration of renewable distributed energy sources increases the
challenges for distribution systems operators to keep the voltage variations within the …

As the grid impedance increases, the grid strength gradually becomes weak. In order to
have good output characteristics in weak grid, grid-forming (GFM) inverters with LCL filter …

As the photovoltaic (PV) sources capacities in distribution networks continue to grow, more
operational challenges are expected to be encountered. One of these challenges is the …
