This paper examines the design principles of smart photovoltaic power sources. It explores the devices that transform traditional photovoltaic sources into smart electrical energy systems and describes the hardware required to implement these intelligent functions. The study investigates the structural principles of photovoltaic sources with reconfigurable internal topologies. It demonstrates the feasibility of employing switched connections instead of fixed wiring for interconnecting solar cells within a panel, noting that such connections can be dynamically controlled. The use of field-effect transistors is identified as the most suitable switching element. The paper contrasts the conventional approach, where source topology is modified by connecting or disconnecting individual photovoltaic cells, with an alternative method utilizing a switching unit to arrange elements in parallel or series configurations. A practical implementation of a photovoltaic panel is proposed, featuring cells interconnected via commutation cells under the control of a programmable microcontroller. Furthermore, the principle of forming an electrical grid incorporating these smart photovoltaic panels is presented. Two distinct configurations are realized: one utilizing traditional communication networks and another employing hybrid power-communication lines and devices. Key advantages of smart photovoltaic sources are highlighted, emphasizing that power systems equipped with such sources benefit from the dynamic optimization of generation parameters. Finally, the principles for developing a data exchange communication protocol between smart photovoltaic sources are described, followed by concluding remarks.
