6 FAQs about [Distributed photovoltaics are good for inverters]

Are distributed photovoltaics a threat to electric power systems?

Rapid growth of distributed photovoltaics (DPV) has upended how engineers traditionally think about electric power systems. Consumers now increasingly generate their own power and feed it to the grid. Poorly managed DPV poses distinct risks for power systems as penetration increases.

How to choose a photovoltaic inverter?

The inverter of the photovoltaic power generation system should have the ability to adjust the power factor within the range of 0.95 leading to 0.95 lagging. If necessary, it should have the method predetermined by the State Grid Corporation, according to the voltage of the grid connection point within its reactive power output range.

How has distributed photovoltaics impacted power system planners & operators?

Rapid growth of distributed photovoltaics (DPV) has upended how power system planners and operators think about electricity grids. Falling costs of solar electricity have made on-site generation and consumption a low-cost option for access to new, clean power globally.

How does a DPV inverter work?

A predefined power reserve is kept in the DPV inverter, using flexible power point tracking. The proposed algorithm uses this available power reserve to support the grid frequency. Furthermore, a recovery process is proposed to continue injecting the maximum power after the disturbance, until frequency steady-state conditions are met.

Which inverter capacity should a PV system use?

As such, systems are generally designed to use the smallest appropriate inverter capacity, all else being equal. PV systems generate output at their peak DC capacity only for some hours of any given year, and less than 1 percent of the energy produced will be at a power above 80 percent capacity (Pulumbarit 2023).

Can distributed solar PV be integrated into the grid?

Traditional distribution planning procedures use load growth to inform investments in new distribution infrastructure, with little regard for DG systems and for PV deployment. Power systems can address the challenges associated with integrating distributed solar PV into the grid through a variety of actions.
