The Distribution Interconnection Handbook serves as a comprehensive guide for facilitating the interconnection of distributed energy resources (DERs) to the electrical distribution system. It outlines the procedures, requirements, and technical considerations for connecting DERs such as solar photovoltaic (PV) systems, wind turbines, battery storage systems, and microgrids to the distribution grid. Here's an overview of what it typically includes:
Introduction to Interconnection: The handbook provides an introduction to distributed energy resources and their role in the modern electric power system. It explains the importance of interconnection standards and procedures in enabling the seamless integration of DERs into the distribution grid.
Interconnection Process Overview: It outlines the step-by-step process for interconnecting DERs to the distribution system, from initial application submission to final system commissioning. This includes procedures for completing interconnection applications, conducting feasibility studies, and executing interconnection agreements with the utility.
Technical Requirements and Standards: The handbook details the technical requirements and standards that DERs must meet to ensure safe, reliable, and grid-compatible operation. This includes specifications for equipment performance, power quality, voltage regulation, frequency response, and protection coordination.
Interconnection Application Requirements: Guidelines for preparing and submitting interconnection applications are provided, including documentation requirements, system design specifications, and engineering drawings. The handbook also explains the process for reviewing and approving interconnection applications by the utility.
Feasibility Studies and Impact Assessments: Procedures for conducting feasibility studies and impact assessments are outlined to evaluate the potential impacts of DER interconnections on the distribution system. This includes assessing voltage and thermal impacts, power flow analysis, and protection coordination studies.
Interconnection Agreement Terms and Conditions: The handbook explains the terms and conditions of interconnection agreements between DER owners and the utility, including technical requirements, liability provisions, metering and billing arrangements, and dispute resolution procedures.
Safety and Compliance: Safety considerations and compliance requirements for DER interconnection are emphasized, including electrical safety standards, grid protection requirements, and compliance with local regulations and building codes.
Grid Integration and Control Strategies: Strategies for integrating DERs into the distribution grid and optimizing their operation are discussed, including advanced control and communication technologies, grid-friendly DER inverters, demand response programs, and energy management systems.
System Monitoring and Performance Evaluation: Guidelines for monitoring and evaluating the performance of interconnected DERs are provided, including data collection, analysis, and reporting procedures. This helps ensure that DERs operate in compliance with interconnection standards and contribute to grid reliability and stability.
Training and Education: The handbook emphasizes the importance of training and education for DER owners, installers, and operators to ensure proper understanding of interconnection procedures, technical requirements, and safety protocols.
By providing clear guidance and procedures for interconnecting distributed energy resources to the distribution grid, the Distribution Interconnection Handbook facilitates the deployment of renewable energy and other DER technologies, promotes grid modernization and resilience, and supports the transition to a more sustainable and decentralized energy system.
