Appraisal of Constraints Impeding the Integration of Distributed Energy Resources Network

Non-linear power flow impediments and uncertain power generation with variations from renewable generation resources put artificial constraints on distributed energy resources (DERs) network, which subsequently affects power delivery at the demand side. Generation intermittency coupled with load variability subjects the entire DERs integrated power scenario into a complex regime. This inevitably, requires system regulation intelligence to impact optimal scheduling management for an assured power delivery, and to minimize network congestion. Available literatures have usually, lumped distributed renewable generation impediments saliently, to support objectives for developing frameworks for control strategies. The paper seeks to review the causes and characteristics of the constraints that threaten the integration of distributed renewable generation, and also the consequential effect these challenges pose to the network. It further proposes applicable reliability performance indices to support design analysis of DERs grid integration. The vulnerabilities are mostly developed through subsystems of the DERs system namely; generation source, network composition and demand side. The varying impact of the constraints affect the reliability of the system, hence the study.
