6 FAQs about [Solar power generation active and reactive]

What is active and reactive power management in large photovoltaic power plants?

This study proposes an algorithm for active and reactive power management in large photovoltaic (PV) power plants. The algorithm is designed in order to fulfil the requirements of the most demanding grid codes and combines the utilisation of the PV inverters, fixed switched capacitors and static synchronous compensators.

Can reactive power control cope with significant PV generation fluctuations?

To simulate the capability of reactive power control to cope with significant PV generation fluctuations, the PV generation profile for a partly cloudy summer day was chosen. The resulting PV generation factors are shown in Fig. 4.

Can reactive power be used in a PV system?

However, high PV penetration in the electricity grid is known to lead to numerous operational problems such as voltage fluctuations and line congestions, which could be eased by utilizing the reactive power capability of PV systems.

How are active and reactive power related?

Active and reactive power are related through the power factor according to the following set of equations: (3) p i g = s i g ⋅ cos ϕ i g (4) q i g = s i g ⋅ sin ϕ i g (5) s i g = (p i g) 2 + (q i g) 2 (6) q i g = p i g ⋅ tan ϕ i g, where s i g denotes the apparent power flowing from the PV system.

Can a PV inverter be used as a reactive power generator?

Using the inverter as a reactive power generator by operating it as a volt-ampere reactive (VAR) compensator is a potential way of solving the above issue of voltage sag . The rapid increase in using PV inverters can be used to regulate the grid voltage and it will reduce the extra cost of installing capacitor banks.

Can an inverter use a pure reactive power generator at night?

Retaining the active power at zero in Fig. 8b indicates that the inverter has the ability to inject pure reactive power without consuming active power from the grid. Finally, the results validated that this inverter model can be used during the night as a pure reactive power generator without consuming any active power from the grid.
