INTELLIGENT LOCAL GRIDS FOR HIGH PV PENETRATION

摘要

In this paper the potential for demand side management for the operation of the local grid was investigated. Simulations of a concrete network cell show that voltage limits could be reached when more and more PV installations are set up. The BEMI control scheme for demand side management in local grids was presented. In a 100 % scenario electrical energy from renewables will be used for serving parts of the heat demand also. Considering this demand in an energy management system can foster keeping the voltage limits, raising the hosting capacity of local grids for renewables and reducing network losses.
