Power systems are undergoing a rapid change in generation mix due to the growth of inverter-based resources (IBRs) such as wind, solar, and battery energy storage.  The dynamic behavior of the Bulk Power System (BPS) that has typically been driven by synchronous machines is increasingly influenced or even largely determined by IBRs.  Stability challenges related…

As solar energy becomes a bigger part of the generation mix, grid operators need better visibility of how much solar power the system is producing. Then they can optimally dispatch solar and other energy sources to balance the generation and demand. Improving solar forecasts will allow the electric grid to be more flexible and adapt…

Power system operators and network owners rely on power system modelling and simulation to maintain secure operation of power systems in real time. Conventional power system simulation models, typically referred to as root-mean square (RMS) models, have been used worldwide by all major network owners and system operators for predicting the response of power systems…

For many years we have been talking about the ambitious Danish goal of 50% of electricity supply from wind power by 2020 and the vison of independence from fossil fuels for the country by 2050. Today electricity generation based on renewable energy sources (RES) constitutes almost 2/3 of the demand. We are now very close…

Distribution-connected PV inverters with advanced functionality, also known as “smart inverters”, have become mainstream in recent years.  Analyses and field experience have demonstrated that smart inverters are a cost-effective alternative to achieve higher penetration of PV in distribution circuits and at the system level.  However, the full potential of smart inverters is yet to be…
