About This Course

Today’s energy grid is changing. We are seeing more renewable energy, the implementation of smart grid as well as the ever increasing use of high speed switching loads. These advances promise increased reliability but they also cause more power quality issues. Power quality is commonly defined as the power grid’s ability to supply a clean and stable power flow as a constantly available power supply. The power flow should have a pure sinusoidal wave form and it should remain within specified voltage and frequency tolerances. No real-life power source is ideal.

In today’s electrical networks, deviations from these ideal conditions are frequent due to increasing non-linear and other loads disturbing the grid. Power generation is also becoming more complex with new players and technologies entering the business, which used to be a fairly stable operating environment. All this adds new challenges to power grid operators.
