Abstract. The analysis presented in this paper indicates that the FM radio spectrum is underutilized in the areas of the continental United States that have a population of 100000 or less. These locations have vacant FM radio spectrum of at least 13 MHz with sufficient spectrum spacing between adjacent FM radio channels. The spectrum spacing provides the required bandwidth for data transmission and provides enough bandwidth to minimize interference introduced by neighboring predicted and unpredicted FM radio stations and other low-power short-range Internet of Thing (IoT) devices. To ensure that low-power short-range IoT devices maintain reliable communications vacant radio spectrum, such as the FM radio spectrum in these areas, will need to be used through cognitive radio.

Grid-Connected Microgrid Battery Energy Storage Systems

Overview of Technical Specifications for Grid-Connected Microgrid Battery Energy Storage Systems

A. Rahman Khalid, et. al

Department of Electrical and Computer Engineering, Florida International University

Abstract: Increasing distributed topology design implementations, uncertainties due to solar photovoltaic systems generation intermittencies, and decreasing battery costs, have shifted the direction towards integration of battery energy storage systems (BESSs) with photovoltaic systems to form renewable microgrids (MGs). Specific benefits include, but are not limited to, seamless switching and islanding operations during outages and ancillary grid services. The evolution of battery chemistries and other components has also further enhanced practicality; however, developing these multifaceted MGs involves complexity in the design process. Consequently, stakeholders rely on connection standards and operational requirements to guarantee reliable and safe grid-connected operations.

This paper presents a technical overview of battery system architecture variations, benchmark requirements, integration challenges, guidelines for BESS design and interconnection, grid codes and standards, power conversion topologies, and operational grid services. In addition, a comprehensive review of the control strategies for battery equalization, energy management systems, communication, control of multiple BESSs, as well as a discussion on protection blinding and intentional islanding using BESSs is also provided. Finally, a discussion of the islanded and black start operation results for time-based analysis and standard validation of a 3MW/9MWh BESS in a grid-connected MG at the Florida International University (FIU) Engineering Campus is presented.

Potato Latkes & Orange Juice

Traditional Hanukkah foods (Spoon University) are often fried or cooked in oil, symbolizing the miracle of the oil that lasted eight days in the rededication of the Second Temple in Jerusalem.

Latkes (Potato Pancakes): Grated potatoes mixed with onions, eggs, and flour, then fried until crispy. They are often served with applesauce or sour cream.

Sufganiyot (Jelly-filled Doughnuts): Deep-fried doughnuts filled with jelly or custard and dusted with powdered sugar. They represent the oil that miraculously burned for eight days.

Brisket: Slow-cooked beef brisket is a popular main course for Hanukkah dinners.

Applesauce: Often served as a topping for latkes or as a side dish.

Matzo Ball Soup: While traditionally associated with Passover, some families also serve matzo ball soup during Hanukkah. It consists of light, fluffy dumplings made from matzo meal in a chicken broth.

Kugel: A baked casserole dish that can be sweet or savory, made with noodles, potatoes, or other ingredients.

Chocolate Gelt: Chocolate coins wrapped in gold or silver foil, often used in the game of dreidel.

Dreidel Cookies: Cookies shaped like the spinning top used in the traditional Hanukkah game of dreidel.

Cheese: In reference to the story of Judith, who is said to have fed cheese to an enemy general to make him thirsty and then gave him wine to make him drunk.

Crime Prevention Through Environmental Design

The most widely cited standard on school security in the United States is the Crime Prevention Through Environmental Design guidelines developed by the National Institute of Justice . CPTED is a multidisciplinary approach to deterring criminal behavior through the design and management of the built and natural environment. It emphasizes the importance of designing schools and their surroundings in a way that maximizes natural surveillance, territoriality, and access control, while minimizing opportunities for crime and creating a sense of ownership and community.

CPTED guidelines have been adopted by many schools and law enforcement agencies across the country and are often referenced in school safety plans, security assessments, and training programs required by the Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act.

Telecommunications Service Entrance Room

Designing a Telecommunications Service Entrance Room (SER) involves careful consideration of various factors to ensure the effective and reliable operation of the telecommunications infrastructure. Here are some typical challenges associated with designing a SER:

Space Constraints:
- Limited space can be a significant challenge when designing a SER, especially in existing buildings where retrofitting may be necessary.
- Adequate space is needed for equipment racks, cable management, and future expansion.
Power and Electrical Requirements:
- Ensuring a stable and reliable power supply for the equipment is crucial. This involves considerations for power redundancy, uninterruptible power supply (UPS) systems, and proper grounding.
- Compliance with electrical codes and regulations must be addressed.
Cooling and Ventilation:
- Telecommunications equipment generates heat, and effective cooling is essential to prevent overheating and ensure optimal performance.
- Adequate ventilation and air conditioning systems must be designed to maintain a suitable operating temperature.
Cable Management:
- Managing and organizing a large number of cables can be challenging. Proper cable routing, labeling, and documentation are essential for troubleshooting, maintenance, and future upgrades.
Security:
- Physical security is crucial to protect the telecommunications equipment from unauthorized access and potential tampering.
- Access control systems, surveillance, and security policies need to be implemented.
Environmental Considerations:
- Depending on the location of the SER, environmental factors such as humidity, dust, and potential exposure to water or other contaminants need to be addressed.
Scalability and Future Expansion:
- Designing the SER with future growth in mind is important. The infrastructure should be scalable to accommodate additional equipment and technologies as the organization’s needs evolve.
Equipment Selection:
- Choosing the right telecommunications equipment for the specific needs of the organization can be challenging. Factors such as compatibility, performance, and vendor support must be considered.
Interoperability:
- Ensuring that different telecommunications systems and equipment can work seamlessly together is crucial for the overall effectiveness of the SER.
Reliability and Redundancy:
- Designing for high reliability and redundancy is essential to minimize downtime. This involves redundant power supplies, network connections, and backup systems.

Addressing these challenges requires a multidisciplinary approach involving telecommunications experts, electrical engineers, facility managers, and IT professionals. Regular maintenance and updates to the SER design should also be part of the overall strategy to ensure ongoing efficiency and effectiveness.
