6. Assessing the Renewable Energy Sources Integration Through a Series of Technical Performance Indices Using DIgSILENT PowerFactory DPL

The increasing penetration of intermittent energy sources in existing power systems heavily impacts the planning and operational processes of system operators. Therefore, refined approaches are required to address the techno-economic issues introduced by the stochastic nature of renewable energy sources, in an attempt to harness the maximum benefit possible. To address these challenges, this work capitalizes on a set of technical performance indices. These indices are attempting to quantify some operational impacts by providing an operational and/or long-term planning tool for assessing the renewable energy penetration in transmission networks. The modeling and simulation case studies are facilitated within the powerful grid simulator DIgSILENT which enables for fast and reliable execution of a wide spectrum of computing procedures. In particular, this chapter showcases how DIgSILENT’s programming language (DPL) is utilized to create several automated scenarios that may explore potential topologies of a test system as per the systems’ operators and planners’ possible interests.
