Sliding mode control of a DC distributed solar microgrid

摘要: This paper proposes a standalone distributed photovoltaic system which includes two independently controlled solar power sources, battery storage and resistive load. Each of the PV panels consist cascaded DC-DC boost converters through independent sliding mode controllers. The design simulation supervisory controller are also discussed. First, maximum point tracking (MPPT) control strategy is introduced to maximize simultaneous energy harvesting from both renewable sources. Then, according generation available at each source state charge in battery, four contingencies will be considered controller. Moreover, interfacing common DC bus as voltage sources under Pi-sliding Numerical simulations demonstrate accurate operation functionality MPPT algorithm operating condition.
