Simulations are based on a real case study relevant to a microgrid in a rural area: Ngarenanyuki Secondary School in Tanzania. The proposed methodology is used to design a new microgrid based on photovoltaic and energy storage system, comparing the results obtained adopting different modeling approaches and different technologies.
Controller and energy management system modeling. Many microgrids receive power from sources both within the microgrid and outside the microgrid. The methods by which these microgrids are controlled vary widely and the visibility of behind-the-meter DER is often limited.
Resilience, efficiency, sustainability, flexibility, security, and reliability are key drivers for microgrid developments. These factors motivate the need for integrated models and tools for microgrid planning, design, and operations at higher and higher levels of complexity.
Section 3 presents a simple case study consisting in the robust optimization of a small microgrid with battery storage and aiming at characterizing the influence of the battery model in the design process. Section 4 gives the results associated with this case study and conclusions are presented in Section 5.
Abstract: Battery energy storage systems are fundamental components in microgrids operations, therefore it is important to adopt models suitable to properly evaluate the performance of these electrical systems.
Industry and the academic fields have developed and are developing sophisticated economic models on how utility costs and revenues affect the electricity rates offered to consumers. These models are a source of calculations for consumer savings and energy equity which, in turn, drive the outcomes of microgrid planning and design tools.
