Integrated Electrical System
Overview
The system can be broken down into an initial PV solar cell array function or component that is responsible for the solar panel or PV ISDM element representing a real-world situation with solar irradiance and cell temperature. The battery bank operates in conjunction to the DC Bus acting as an entire unit that is the PV – battery charger. Prior the battery’s operation within the system, the DC-DC boost (further discussed in the Discussion and Conclusion section of this investigative report) is designed to operate to the design requirements for the voltage input and output ratings. The integration of the simulated DC/AC inverter allows for the appropriate connection from the battery to the step-up transformer.
Approach
Power source is the PV panel with a nominal power rating of 260W. A PV-battery charger converts the solar power to supply DC link, which is rated to be 48V DC. The battery bank is rated as 48V nominal and 4.8kWH in capacity. A DC to single-phase AC converter supplies AC loads, which is rated as 230V (RMS) and 50Hz.
