6 FAQs about [Photovoltaic power generation system without energy storage]

What is a PV system without energy storage?

For a PV system or WTG without energy storage, the output power is random and limited by the environmental conditions. PV system has no power reserve or inherent rotor inertia. Furthermore, for the two-stage PV system, instead of the mimic swing equation control in VSG, its DC-link voltage loop is required through the AC/DC inverter.

Can a two-stage PV system support Fr without energy storage?

In this paper, to introduce the inertia and FR abilities for two-stage PV generation without energy storage, a novel VSG control method is proposed. This method maintains a part of the active power by PRC control and combines VSG technology to enable the PV system to support FR in the island microgrid.

Can virtual synchronous generator control provide frequency support without energy storage?

In this study, a novel virtual synchronous generator (VSG) control for PV generation was introduced to provide frequency support without energy storage. PV generation reserve a part of the active power in accordance with the pre-defined power versus voltage curve.

Can a virtual synchronous generator control a microgrid without energy storage?

Abstract：In autonomous microgrids frequency regulation (FR) is a critical issue, especially with a high level of penetration of the photovoltaic (PV) generation. In this study, a novel virtual synchronous generator (VSG) control for PV generation was introduced to provide frequency support without energy storage.

What is photovoltaic virtual synchronous generator (PV-VSG)?

Photovoltaic virtual synchronous generator (PV-VSG) technology, by way of simulating the external characteristics of a synchronous generator (SG), gives the PV energy integrated into the power grid through the power electronic equipment the characteristics of inertial response and active frequency response (FR)—this attracts much attention.

Is there a hybrid electric/hydro storage solution for standalone photovoltaic applications?

The given research paper discusses a hybrid electric/hydro storage solution for standalone photovoltaic applications in remote areas. (Ruisheng L, Bingxin W, Xianwei L, Fengquan Z, Yanbin L. Design of wind–solar and pumped-storage hybrid power supply system. In: Power and energy society general meeting. IEEE; 2012. p. 1–6.)
