How can you ensure reliable and consistent power delivery to customers?

Power delivery is a crucial aspect of electrical engineering, especially for electric utilities that serve millions of customers. Reliable and consistent power delivery means ensuring that the voltage, frequency, and quality of the electric current are maintained within acceptable limits, and that the power outages are minimized or avoided. How can you achieve this goal as an electrical engineer? Here are some tips and best practices to follow.

1 Understand the power system

The first step is to have a thorough knowledge of the power system you are working on, including its components, characteristics, and behavior. You need to know how the generation, transmission, distribution, and consumption of electricity are interconnected and interdependent, and how they affect each other. You also need to know how to model, analyze, and simulate the power system using software tools, such as MATLAB, PowerWorld, or PSS/E, to identify potential problems and solutions.

In addition to the above listed effects, power quality has a direct impact on power reliability. You ought to ensure quality before you ensure reliability. Power electronic devices, arcing devices, load switching, large motor starting, embedded generation, sensitive equipment, damage from storms and the environment, and network equipment and design are some of the issues that might cause problems with power quality. When production processes become more complex and demand a higher liability level, finding a way to improve the power quality at the load side becomes crucial. This includes criteria like uninterrupted energy supply and reduced harmonic distortion. FACTS devices might be able to solve issues of power quality.

2 Design for reliability

The second step is to design the power system for reliability, which means ensuring that it can withstand and recover from various faults and disturbances. You need to consider the load demand, the environmental conditions, the equipment specifications, and the safety standards when designing the power system. You also need to apply appropriate protection and control schemes, such as circuit breakers, relays, fuses, transformers, and generators, to prevent or mitigate damage and disruption.

Conduct a thorough analysis of the expected load demand on the power system. Anticipate peak loads, fluctuations, and variations in demand over time. Designing with an understanding of the load profile ensures the system can meet customer requirements under varying conditions. Specify equipment with appropriate ratings, capacities, and reliability characteristics. This includes transformers, generators, switchgear, and other critical components. Selecting high-quality equipment from reputable manufacturers contributes significantly to the system's overall reliability.

3 Monitor and maintain the power system

The third step is to monitor and maintain the power system regularly, which means checking its performance, condition, and operation. You need to use sensors, meters, and communication devices to collect and transmit data from the power system, such as voltage, current, frequency, power factor, and harmonics. You also need to use software applications, such as SCADA, DMS, or EMS, to process and display the data, and to control and optimize the power system.

4 Plan for contingencies

The fourth step is to plan for contingencies, which means preparing for possible scenarios that could affect the power delivery, such as equipment failures, natural disasters, cyberattacks, or human errors. You need to conduct risk assessments, contingency analyses, and emergency plans to identify and prioritize the potential threats and impacts, and to define the actions and resources needed to respond and restore the power delivery.

5 Implement smart grid technologies

The fifth step is to implement smart grid technologies, which means using advanced devices and systems that can enhance the efficiency, reliability, and security of the power delivery. You need to integrate renewable energy sources, energy storage devices, microgrids, and distributed generation into the power system, to diversify and balance the supply and demand of electricity. You also need to use smart meters, smart switches, smart inverters, and smart appliances to enable bidirectional communication and control between the power system and the customers.

6 Learn from best practices

The sixth step is to learn from best practices, which means studying and adopting the proven methods and standards that have been used by other electric utilities or organizations to ensure reliable and consistent power delivery. You need to follow the guidelines and regulations of the relevant authorities, such as NERC, IEEE, or IEC, to comply with the quality and safety requirements of the power delivery. You also need to benchmark and compare your performance and practices with the industry leaders and peers, to identify and implement the best practices.

The best way to ensure relatable power supply is by better forecasting, thought we have infra day/week/month model but we still are in no feat to achieve the 95% precision. The key reason behind the later deficit is due to lack of awareness and declining interest towards core profession.
