| Popis: | This work deals with the control of a solar photovoltaic array and a battery storage integrated into a grid. It has versatile control strategy as it provides with maximum power point tracking, battery charging/discharging and a grid current at unity power factor. This configuration along with its control helps in feeding a constant power to the grid and maintains the controlled power dynamics in the system. The control performs a voltage control of the boost converter, current control of grid and DC-link voltage control along with current control of the battery and adapts itself according to the environmental conditions such as no/low solar insolation and absence of battery storage. The proposed system is designed for a maximum power of 5 kW and simulated in MATLAB-based environment. Test results on a prototype developed in the laboratory verify the simulated results. Under steady-state condition, the total harmonic distortions of grid voltage and current are within the range of an IEEE 519 standard. Simulations and experimental results of the proposed system are demonstrated for various dynamic changes. |
