Читать книгу Smart Solar PV Inverters with Advanced Grid Support Functionalities - Rajiv K. Varma - Страница 28

Solar PV systems are typically classified as IBRs or DERs when connected to bulk power systems or distribution systems, respectively. The impacts of solar PV systems occur both at a local level, i.e. on the interconnecting distribution feeder or substation, or at the interconnected bulk power system level, or both. A summary of the impact of high penetration of solar PV systems in different countries is presented in the IEA PVPS Program report [18, 19]. A detailed coverage of technical challenges and experiences with high levels of PV integration is presented in [3, 4,20–27].

A summary of the adverse impacts of high penetration of solar PV systems is presented below. However, a detailed coverage of these impacts and their potential solutions utilizing smart inverters are provided in subsequent chapters. Although the challenges are described with respect to solar PV systems, they also apply to other IBRs such as wind generators.
