### Existing Commercial Building  
An existing commercial building situated on 2000 m\({}^{2}\) of land in an industrial park in Suzhou, Jiangsu, China (120\({}^{\circ}\)26\({}^{\prime}\) E and 31\({}^{\circ}\)22\({}^{\prime}\) N) serves as a case study for further validating the proposed framework. The specific building structure is shown in Figure 11b. It features a 200 kW photovoltaic power generation system. The evaluation results of the existing system are shown in Table 8. Commercial buildings exhibit high energy consumption density, significant seasonal and temporal fluctuations, and considerable demand for lighting and air conditioning, along with the potential for renewable energy utilization. It contains various loads, including elevators, network equipment, water heaters, lighting, monitoring equipment, and sockets, as well as electric vehicle charging stations occupying at least 10% of its parking space. The maximum annual load is 462 kW. The building has a limited load capacity and requires moderate power supply reliability. Thus, a single-ended radial structure with a single-pole bus connection is adopted, \begin{table}
