HASSAN, M. Desing of Photovoltaic Power Plant with Energy Accumulation for Commercial Object [online]. Brno: Vysoké učení technické v Brně. Fakulta elektrotechniky a komunikačních technologií. 2025.
The master thesis written by Mamoon Hassan focuses on the design and evaluation of a photovoltaic power plant with integrated battery energy storage for a commercial building. The student successfully met most of the assigned objectives, including system topology review, legislative analysis, simulation of two system variants using PV*SOL, and a detailed cost-benefit analysis. The work demonstrates significant effort and independence, with a well-structured approach to simulation and financial modeling. However, the thesis lacks systematic depth in several areas. Some assumptions in the design are not fully justified, and documentation of important elements like protection schemes, grid compliance, or battery sizing rationale is insufficient. The level of activity during the project was uneven, with well-developed sections contrasting with others that appear rushed or superficial. The language and grammar throughout the thesis need improvement, as the text contains frequent minor errors and informal expressions that reduce academic clarity. Despite these weaknesses, the thesis provides a technically sound and economically viable design solution, and shows that the student is capable of applying engineering tools and methods to practical problems. With a more careful and structured approach, particularly in technical justification and formal writing, the thesis could have reached a higher standard. Nevertheless I recommend thesis for final defense and evaluate it with 78p.
The master’s thesis by student Hassan, titled “Design of Photovoltaic Power Plant with Energy Accumulation for Commercial Object” focuses on the design of a photovoltaic power plant with battery storage for a commercial facility. The student developed two design variants using the simulation software PVSOL, carried out an economic analysis, and prepared project documentation for the selected variant. In terms of content, the thesis is relatively extensive and thematically well-structured. The introductory part summarizes basic topologies of PV systems with storage, including a comparison of AC, DC, and hybrid configurations, and also provides an overview of relevant legislation, including recent changes under the LEX OZE III package. For the PV system design, the student used up-to-date climate data for the Brno region and applied a realistic load profile. He correctly performed a comparison of energy yields, self-sufficiency, battery losses, and investment returns. The financial analysis includes the calculation of IRR, cost per kWh, and a payback period of approximately 6 years for both variants. The technical design itself, however, contains several shortcomings. Some of the proposed inverters are overloaded by more than 110%, which is not suitable for long-term operation. The project documentation includes only a basic single-line diagram; for actual implementation, it lacks at least a site layout, panel positioning, and building sections with PV installations. Some of this information is partially included in the PVSOL-generated reports. Furthermore, while the design refers to requirements from the Distribution System Operation Rules (PPDS) and the EU RfG regulation, these are not sufficiently explained or supported by parameter settings of the equipment used. The thesis text contains numerous language errors and stylistic inconsistencies, which sometimes reduce clarity. A more thorough language revision is recommended, especially for technical descriptions and figure captions. In summary, the student has fulfilled the assignment in full. The thesis demonstrates a solid level of technical and economic analysis, although some areas (component design, legislation, documentation) would benefit from deeper treatment and more precise execution.
