DSSE as a tool for hosting capacity assessment in European-type distribution grids

The use of distribution system state estimation (DSSE) can enhance the hosting capacity of an electrical distribution system (DS). DSSE allows for an accurate assessment of the DS state, to integrate a higher share of distributed energy resources. However, due to the low rate of the advanced metering infrastructure deployment in several European countries, some customers still not equipped with smart meters. In turn this limits the implementation of DSSE in the DS. Furthermore, most of distribution system operators consider the constant power load model in carrying out the power flow analysis. This leads to get biased results because of relying on an inaccurate load model.
