Harmonische Probleme in Energiespeicherkraftwerken

Er zijn meerdere normen die niet alleen eisen stellen aan de Totale Harmonische Vervorming in de spanning (THDu), maar ook aan de maximale individuele harmonische spanningen zoals o.a. de NEN-EN50160, IEC61000 reeksen. Volgens de EN50160 norm dient de THDu niet groter te zijn dan 8% voor 95% van de tijd gedurende een week.

What is a harmonic problem in wind power plants?

Another serious harmonic problem in wind power plants might occur when more than one wind power plant is connected to each other with PCC points as shown in Fig. 13.a and when they are used at 80% nominal capacity. Harmonic problem arises when the third plant reduces its power capacity from 80% to 0%.

How to reduce harmonics in solar energy systems?

Recently, different methods have been used for harmonic elimination in solar energy systems. Resilient Direct Unbalanced Control (RDUC) method is one of them. It is used to reduce harmonics in the integration of solar energy systems, especially in distributed generation systems (DGs).

What problems do harmonics cause in electrical power systems?

Harmonics cause technical and economic problems in electrical power systems such as additional losses, additional voltage drops, resonance events, change of power factor . In electrical power systems, the current and voltage are desired to be at a frequency of 50 Hz and in a form close to the sinus curve.

What is a harmonic problem?

Harmonic problem arises when the third plant reduces its power capacity from 80% to 0%. In such a case, the measured current and voltage harmonic components are shown in Fig. 13.b.

Can a predictive model reduce harmonic distortion in a PV system?

In another study on harmonic problems in PV systems, an adaptive filter based on a predictive model is used for reducing the total harmonic distortion . The model is applied to a single-phase standalone PV system by adopting least mean square (LMS), normalized LMS (NLMS) and leaky LMS algorithms to verify the method.

How are energy sources harnessed?

Each source is harnessed using specific methodologies, including photovoltaic solar panels, wind turbines, geothermal heat pumps, subsea turbines, and biofuel plants (Alhuyi Nazari et al., 2021). These technologies have paved the way for harnessing nature's energy abundance and converting it into electricity.
