Photovoltaic Inverter System Reactive Power Compensation
Modern photovoltaic (PV) inverter systems have evolved beyond simple DC-AC conversion to become sophisticated grid management assets. Among their most valuable advanced functionalities is
Most grid connected PV inverters only produce active power as default to supply the loads directly. As a result, the grid is supplying less active power, but the same amount of reactive power, this will reduce the power factor of the whole system. That is why the reactive power compensation function is becoming more necessary.
A simple way is to set a fixed value of reactive output power or to change the PF into certain value on inverter. Solution 2. Dynamic Reactive Power Compensation Static reactive power compensation is a good option especially when the loads always consume same amount of active power and same amount of reactive power.
Reactive power compensation in a solar power system offers several benefits: Many utilities require solar installations to manage reactive power to ensure grid stability. They assess the power factor of the system, and if it falls below their standards, penalties or extra charges for power adjustment may apply.
Photovoltaic (PV) system inverters usually operate at unitary power factor, injecting only active power into the system. Recently, many studies have been done analyzing potential benefits of reactive power provisioning, such as voltage regulation, congestion mitigation and loss reduction.
