Resumen
In order to determine the amount of distributed generation that can be accommodated in the
medium voltage distribution feeders of EMPRESA ELÉCTRICA REGIONAL CENTRO SUR
C.A. (CENTROSUR), a methodology is proposed to calculate the Photovoltaic Hosting
Capacity (PVHC). This capacity is not a fixed calculation with a single result, but a range of
values defined by; the grid input data, criteria and limits established in international
standards and local regulations. Five analysis criteria are proposed to determine the PVHC of
the feeder. The basis of analysis corresponds to a hybrid iterative and deterministic
methodology based on time series analysis, which consists of a systematic procedure of
insertion of Photovoltaic Systems (PVS) and verification of the electrical parameters of the
grid; this is done through simulations using scripts developed in Python programming
language; which will allow running power flow and short circuit simulations in the distribution
systems analysis package; CYMDIST, of the CYME software. The simulations are performed
with active generation quantities of the SFVs increasing at given steps up to a set limit
subject to configuration. As results of the simulations, graphs are presented that identify SFV
penetration safety zones, as well as minimum and maximum penetration levels for
different installation scenarios.
