Novel Method for identifying maximum Renewable Energy Penetration in Distribution Grids

Abstract

With more and more integration of renewable energy sources into the grid, electrical network structure is experiencing significant changes which causes existing power system study tools and algorithms need to be developed again. This paper presents a novel approach to obtain maximum power capabilities in distribution grids with high penetration of distributed generators. An algorithm is developed for calculating the maximum probabilistic hourly capability for a set of nodes inside the distribution grid, taking into account generators contingencies and MVDC (Medium Voltage Direct Current) links. For the case study presented, the MVDC increase the distributed generation penetration.
