Assessing the Flexibility Provision of Microgrids in MV Distribution Grids

Abstract

This paper provides a methodology to assess the amount of flexibility that lower voltage level grids can provide at the connection point to a higher voltage level grid considering operational characteristics of installed flexibility providing units (FPU), while taking grid constraints into account. A multi-level aggregation process is introduced, with the aim to reduce the computational resources required to aggregate flexibilities of large grids. The methodology is verified using test bench grid models, in order to show its effectivity. Results show that the implementation of a multi-level aggregation reduces the complexity of the problem, while providing accurate results.
