6 FAQs about [Photovoltaic power station inverter power regulation]

Are PV inverters voltage regulated?

In the modern day, the PV inverters are being developed under the interconnection standards such as IEEE 1547, which do not allow for voltage regulations . However, a majority of manufacturers of PV inverters tend to enhance their products with reactive power absorbing or injecting capabilities without exceeding their voltage ratings.

How do PV inverters work?

The inverters used in these plants have to be capable of delivering reactive power automatically, in local control logic, according to two characteristics. The power factor of the PV grid connected plants, and then the reactive power delivered or absorbed, can be a function of the active power injected into the grid (cosφ = f (P)).

How does an inverter regulate voltage levels in a utility grid?

The proposed novel method enables an inverter to inject the required level of reactive power to regulate the voltage levels of the utility grid within specified limits. In the process, the inverter does not absorb active power from the grid for its internal operation.

Can a grid-connected PV inverter control overvoltage and undervoltage?

Generally, a grid-connected PV inverter can be programmed to inject and absorb the reactive power. Hence, both the overvoltage and undervoltage conditions can be regulated using the reactive power control ability. The dq components theory, which will be described in Section 2, can be used to perform the controlling mechanism efficiently .

How can inverters improve the frequency regulation ability of PVPP?

The longer the delays, the weaker the PVPP’s ability to participate in primary frequency regulation. In addition, the optimization of PVPP communication system and control strategy of inverters can help improve the frequency regulation ability of the PVPP, thereby maintaining the frequency stability of the power system. 1. Introduction

Are photovoltaics involved in primary frequency regulation?

Since the frequency of the power system always keep changing, the participation of photovoltaics in primary frequency regulation is time-sensitive. Although many countries have set standards on the response time of photovoltaic frequency regulation, the requirements of these standards are very loose.
