This document presents a new application of the method versatile control based on the continuous calculation of mixed type (CMPN) motivated to improve the transport capacity under tension photovoltaic control (PV) associated with the frame (LVRT) enhancement facilities. PV clusters are connected to the common junction point (CCP) via a direct current DC converter, a capacitor CC interface, an inverter side matrix and a three phase transformer. The DC-DC converter is used for a higher power point after processing in view of the fragmentary open circuit voltage technique. The inverter on the matrix side is used to control the DC connection voltage and terminal voltage on the PCC via a vector control diagram. The necessary versatile necessary controller (PI) based on the CMPN calculation is used to control the electronic circuits due to the fast connection. The implemented calculation is updated, the PI controller increases online without having to calibrate or simplify. The feasibility of the procedure performed steering contrasts with the approach Taguchi based on ideal PI controller, so that patient deemed due to the presence of a fault the table asymmetric symmetric errors and incorrect reconnection circuit breakers permanently. The legitimacy of the versatile control technique is largely determined by reproduction, complete with the programming of MATLAB / Simulink. The LVRT capacity of the frame can be improved by implementing the versatile controlled photovoltaic control systems
