Interconnection Standards are technical specifications that regulate the interconnection of power generation facilities and electricity transmission systems with distributed energy resources (DERs). Their primary purpose is to ensure the safe and reliable integration of renewable energy sources into the electrical grid while maintaining its stability, reliability, and security. The need for Interconnection Standards arose in response to the growing demand for renewable energy, such as solar and wind, in the United States during the early 2000s. The IEEE and NESC developed these standards in conjunction with industry stakeholders, including utilities, regulators, and renewable energy providers.
What are the Applications of Interconnection Standards?
1. The applications include facilitating the seamless integration of DERs, such as solar panels, wind turbines, and energy storage systems, into the electrical grid. DERs are typically installed at the customer’s site, and any excess energy generated is fed back into the grid. Interconnection Standards ensure that the DERs meet the required safety and technical standards to connect to the grid and operate efficiently.
2. Another essential application of Interconnection Standards is ensuring the stability and reliability of the grid for that matter. DERs, particularly wind, and solar, can cause voltage and frequency fluctuations on the grid as they are intermittent sources of energy. Interconnection Standards provide guidelines for the installation and operation of DERs to keep these fluctuations within acceptable limits and prevent grid instability or outages.
3. Interconnection Standards also help improve grid resilience and security by specifying the installation and design of protective equipment, such as inverters, relays, and breakers, to prevent or mitigate the impact of electrical faults or disruptions. They also outline cybersecurity measures to protect the grid from unauthorized access and cyber-attacks. Their widespread adoption has enabled the rapid growth of renewable energy sources and contributed to a cleaner and more sustainable energy future so to speak.
4. Interconnected standards can also support the growth of clean energy by promoting the use of renewable energy sources and other technologies. This can ultimately create new economic opportunities in turn for businesses while reducing overall greenhouse gas emissions.
