A comprehensive review on impact of wind and solar photovoltaic energy sources on voltage stability of power grid

Abstract EN

The concern for ever-increasing demand for electricity, progressive depletion of fossil fuels, reduction in carbon footprint, improved infrastructure reliability, etc.

have encouraged the power utility companies to adopt renewable energy sources in conventional power systems.

The enhanced penetration of non-dispatchable renewable energy sources such as solar photovoltaic (PV) and wind energy into existing distribution and transmission networks had led to various issues of concern regarding system voltage stability.

This paper presents the important issues such as voltage stability based optimum locations and sizing of distributed generation (DG) units, voltage stability assessment, and improvement techniques.

The impact of power system devices such as fixed capacitors, flexible AC transmission system (FACTS), and energy storage system (ESS) on voltage stability of transmission and distribution networks are also investigated.

The review results provide a comprehensive background for the voltage stability investigation in non-dispatchable renewable integrated power systems with major outcomes and findings of future research work in the field of power system stability.
