This paper presents an advanced control of photovoltaic system with battery storage system and shows the coordination of the studied system in order to enhance solar energy utilization. This study proposes an approach of coordinated and integrated control of solar PV generators with battery storage control in order to maintain active and reactive power (P-Q) control and to provide voltage and frequency (V-f) support to the grid instead of a high load addition. The description of the studied system is based on a battery energy storage system based (lithium-ion technology), a DC-DC bidirectional power converter in order to connect the battery to the DC bus, DC-DC converter, voltage source inverter and finally the load and the micro-grid. Consequently, the main contribution of the proposed control methods lies in the coordination between the different controls methods proposed: battery control at the PV side and V-f/P-Q control algorithm at the inverter side. A simulation using the Matlab/Simulink software has been performed, to confirm that the proposed control model is able to provide voltage and frequency support to the grid and to maintain active and reactive power control instead of a high load addition.

Niniejszy artykuł przedstawia zaawansowaną kontrolę systemu fotowoltaicznego z systemem baterii i pokazuje koordynację badanego systemu w celu zwiększenia wykorzystania energii słonecznej. W opracowaniu zaproponowano podejście polegające na skoordynowanym i zintegrowanym sterowaniu generatorami fotowoltaicznymi z kontrolą akumulatorów w celu utrzymania kontroli mocy czynnej i biernej (P-Q) oraz zapewnienia wsparcia napięcia i częstotliwości (V-f) dla sieci zamiast dodawania wysokiego obciążenia. Opis oparty jest na systemie akumulacji energii akumulatora (technologia litowo-jonowa), dwukierunkowym konwerterze mocy DC-DC w celu podłączenia akumulatora do szyny DC, przetwornicy DC-DC, falownika źródła napięcia i wreszcie obciążenie. W związku z tym główny wkład proponowanych metod sterowania polega na koordynacji różnych proponowanych metod sterowania: kontrolą baterii po stronie PV i algorytm sterowania V-f / P-Q po stronie falownika. Przeprowadzono symulację za pomocą oprogramowania Matlab / Simulink, aby potwierdzić, że proponowany model sterowania jest w stanie zapewnić wsparcie napięcia i częstotliwości dla sieci oraz utrzymać kontrolę mocy czynnej i biernej zamiast dodatku o wysokim obciążeniu.
