6 Frequently Asked Questions about “Replacement of photovoltaic power station with high-power generator set”
How are photovoltaic plants different from synchronous generators?
Provided by the Springer Nature SharedIt content-sharing initiative The Photovoltaic (PV) plants are significantly different from the conventional synchronous generators in terms of physical and electrical characteristics, as it connects to the power grid through the voltage-source converters.
Will photovoltaic power replace fossil fuels?
Photovoltaic (PV) power is one of the prominent renewable resources and likely to replace a significant proportion of fossil-fuels in the future. With the increasing penetration of PV power, power system operators will encounter severer challenges [1, 2, 3].
What is the difference between a synchronous generator and a PV?
Unlike synchronous generators, PVs are connected to the power grid through the voltage-source converters (VSCs). Thus, the PVs are significantly different from the conventional synchronous generators in terms of physical and electrical characteristics. Thus the high penetration PVs will deteriorate the frequency stability of power system.
Can high penetration PV work like a synchronous generator with variable inertia?
High penetration PV in power system will bring several critical challenges to the safe operation of power grid including transient stability. To address this problem, the paper proposes a control strategy to help the PVs work like a synchronous generator with variable inertia by energy storage system (ESS).
Do inverter-based photovoltaic power stations have rotating elements?
However, the inverter-based photovoltaic (PV) power stations do not have rotating elements and usually operate under the maximum power point tracking (MPPT) control strategy, which means it could not provide adequate energy, neither kinetic energy nor potential energy, to stabilize the power grid.
How can a VSG model rotational inertia of a synchronous generator?
VSGs could model the rotational inertia of a synchronous generator through coordinating the active power output of the PV power station and an energy storage system (ESS) . Once disturbed, the electrical power stored in the ESS could be exploited to dissipate the unbalanced energy.
