An improved scheme for enhancing the ride-through capability of grid-connected photovoltaic systems towards meeting the recent grid codes requirements

Haidar, Ahmed M. A. and Julai, Norhuzaimin (2019) An improved scheme for enhancing the ride-through capability of grid-connected photovoltaic systems towards meeting the recent grid codes requirements. Energy for Sustainable Development, 50. pp. 38-49. ISSN 0973-0826

Abstract

With the increasing number of solar PV systems, the future grid-connected converters should provide a full range
of services. Such requirements make the operators of the distribution system modify the current grid codes to
ensure the security of the power grid and enhance the LowVoltage Ride-Through (LVRT) capability of renewable
energy resources (RER). Nowadays, in many countries, the smart grid is standardized, and thus, the development
of control strategies for a grid-connected PV system is crucial, particularly with the high level of PV penetration.
Initially, the paper reviews the grid codes for LVRT capability of grid-connected solar PV systems. Furthermore,
the paper proposes an improved protection control strategy for the DC link of grid-connected PV system with
reactive power support to enhance the LVRT during grid faults. The test results presented in this paper have
vindicated the effectiveness of the proposed approach.
