XML Multi-Stage Framework for Analyzing Penetration of Stochastic Distributed Energy Resources and Storage
P. 1-15
P. Paliwal
Abstract (1939 Views) | Full-Text (PDF) (744 Downloads)   |   Highlights
  • A probabilistic framework for analyzing the impact of DER penetration on system planning has been presented.  This adds a new dimension to planning methodology where, in addition to optimal sizing and placement, optimum DER penetration level can also be determined.
  • The penetration level in this work is correlated with the meteorological parameters on hour by hour basis. The formulation proposes the concept of analyzing the DER penetration through Penmin and Penmax. This adequately addresses the intermittent behavior of DERs.
  • A three-stage methodology has been developed to addresses the assessment of DER penetration level. The intermittent nature of DERs may pose up technical issues such as system reliability problem and voltage fluctuation. Thus, in this planning framework, technical problems are given due consideration while simultaneously handling the economic front. In order to enable in-depth economic evaluation, the technical and environmental objectives have been expressed as cost functions.
  • Different planning scenarios have been investigated in order to have an understanding of prioritizing objectives and penetration level from an economical perspective.
