Investigation of Value-Added System Support Functions of PV Systems**

该项目旨在将光伏发电和智能逆变器结合起来，创造电力系统支持功能，增强配电网络，同时产生环保能源。在现有的光伏逆变器运行容量有功功率控制的基础上增加无功功率，可以实现无功功率管理、电压调节、电压通频等电力系统支持功能。因此，多个光伏系统可以通过通信网络聚合，作为可变无功发电机。这为取代电容器组或电抗器在本地配电网中进行无功控制提供了巨大的潜力。** **UNB研究人员将与圣约翰能源公司（SJE）一起进行这项调查，该公司拥有并运营着为圣约翰市及周边地区服务的配电系统。SJE已经确定了将光伏发电整合到其配电系统中的巨大潜在利益，并希望通过智能光伏逆变器从光伏系统中产生千瓦时以外的其他价值。光伏系统支持功能的附加价值可以帮助实现可再生能源在电力市场的更高渗透率，从而通过减少温室气体排放实现环境效益。研究结果可能会使加拿大100多家当地分销公司受益。********

This project aims to combine photovoltaic (PV) generation and smart power inverters to create power system support functions that enhance electricity distribution grids, in addition to generating environmentally-friendly energy. Adding reactive power to the existing active power control of PV inverter operation capacity can enable power system support functions such as management of reactive power, voltage regulation, and voltage & frequency ride-through. As a result, multiple PV systems can be aggregated via communication networks to function as variable reactive power generators. This presents great potential to displace capacitor banks or reactors to conduct reactive power control in local distribution networks. ** **UNB researchers will conduct this investigation with Saint John Energy (SJE), who owns and operates the electrical distribution system serving the city of Saint John and surrounding areas. SJE has identified great potential benefits in integrating PV generation into its distribution system and would like to investigate additional values beyond generating kWh's from PV systems via smart PV inverters. The value added from PV system support functions can help achieve higher penetration of renewable energy in the electricity market, resulting in environmental benefits from reduced greenhouse gas emissions. The research outcome could potentially benefit over 100 local distribution companies across Canada.********
