Multi-Stage Framework for Analyzing Penetration of Stochastic Distributed Energy Resources and Storage
P. Paliwal
Abstract:   (2467 Views)
This paper presents a multi-stage planning framework for analysis of stochastic distributed energy resources (DERs) comprising of solar, wind, and battery storage. The existing models do not consider penetration level analysis in conjunction with sizing, placement, and economic assessment. The main objective of this research is to embed all these dimensions of system planning in one structure. The first stage involves reliability constrained component sizing.  The second stage pertains to placement of DERs based on loss minimization and voltage profile. The third stage is the main thrust of this work which provides exhaustive economic evaluation and cost-benefit analysis. The novelty of this work lies in the consideration of penetration level in backdrop of all three stages. The proposed formulation is implemented on a 33-Bus radial distribution feeder located in Jaisalmer, Rajasthan, India. Four penetration levels viz. 10, 20, 40, and 60 percent have been investigated and analyzed under different planning scenarios. The results facilitate the determination of optimum penetration level.

  • 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.
