Integration Renewable Energy Resources to Weak Grids: Interconnection Challenges
Electrical power transmission systems spread across large geographic areas present significant challenges to engineers. Operating the system stably while maintaining voltage and frequency variations within narrow tolerance margins require careful long-term planning as well as short-term operational planning.
These planning efforts of utility engineers are supported by significant research and development efforts of various international organizations. As a result, power system outages that affect widespread regions are very rare. Over the years, the power system community has acquired significant experience related to the operation of traditional power systems where the generation is predominantly based on synchronous generators. However, the large penetration of renewable energy is expected to present new challenges. The renewable energy generation is interfaced to the transmission system with the use of power electronic converters. The dynamic response characteristics of power electronic based generation are much different from conventional generators. Specifically, the converter-based generators do not contribute to the system inertia and can potentially make the power system vulnerable following system events such as line faults. Key characteristics of renewable energy generators that can affect system stability will be discussed during this presentation.
