Maintaining Grid Stability with Increased Solar PV Integration in Vietnam

March 2023 - With support from the U.S. State Department, Bureau of Energy Resources, Power Sector Program (ENR/PSP), NARUC has published a report titled "Maintaining Grid Stability with Increased Solar PV Integration in Vietnam." This report presents an overview of the existing requirements and directives with regard to voltage control in Vietnam’s power distribution network and puts forth recommendations for enhancing the regulatory framework pertaining directly or indirectly to voltage control in light of increased photovoltaic (PV) penetration.

The analysis centers on the transmission and distribution grid codes currently being enforced in Vietnam, as well as on their amendments. The report includes:

An overview of the Vietnamese electricity market
An analysis of the existing regulatory regime with respect to voltage regulation as depicted in the country’s codes and circulars and a description of what is taking place in practice in Vietnam with respect to the enforcement/application of existing voltage regulations
An analysis of international experience with respect to establishing and implementing voltage regulation standards and obligations for distributed generation from PVs
A set of recommendations to better regulation and practice to the evolving PV generation context of the country
