Abstract

In order to secure the reliability of the power system and to increase the penetration level of distributed energy resources (DERs), requirements such as IEEE 1547 have been revised to strengthen the grid connection standards for DER. This paper proposes a control scheme for smart inverter functions based on IEEE 1547-2018 that satisfy these standards, and introduces a power HILS-based test platform built for verification of smart inverter. Among the smart inverter functions, Volt-var and Frequency-watt allow the curve to be set from the upper level to comply with the interoperability and operation time of enable signals for each function are controlled by references from the upper level. According to the requirement, Volt-var and Frequency-watt are performed via power HILS platform and verified through the measurement results that all of the specified type tests were satisfied.

전력시스템의 신뢰성을 보장하며 분산전원의 수용성을 높이기 위해 IEEE 1547과 같은 표준을 개정하여 분산전원의 계통 연계기준을 강화하고 있다. 본 논문은 이러한 표준을 준수하는 IEEE 1547-2018 기반의 스마트 인버터 기능의 제어 알고리즘을 제안하고, 스마트 인버터 기술의 검증을 위해 구축한 Power HILS 기반의 테스트 플랫폼을 소개한다. 스마트 인버터 기능 중 Volt-var 제어와 Frequency-watt 제어 알고리즘은 상호운용성 표준을 준수하도록 해당 기능의 curve를 상위로부터 설정할 수 있도록 하며, 각 기능의 Enable 신호 시점을 상위 지령에 따라 제어할 수 있도록 하였다. 표준에 따라 Power HILS 테스트 플랫폼을 통해 Volt-var 제어와 Frequency-watt 제어에 대한 형식시험을 수행하였고, 명시된 표준 형식시험을 전부 만족함을 측정 결과를 통해 검증하였다.
