GM 22 Tutorial: Modeling and Planning of Distributed Energy Resources in Distribution System with Open-Source Software (slides)

Because of distributed energy resources (DER), planning of the grid becomes more complex and dynamic for grid planners. Open-source software (OSS) is a flexible solution to supplement and interoperate with existing tools and processes. While there are many OSS tools used in different aspects of utilities, this tutorial focuses on distribution grid modeling and simulation. This tutorial will start with policy initiatives and trends of change for distribution resource planning. Tools for distribution grid simulation, resource planning, and DER modeling will be discussed along with real-world experience and lessons learned. Next, the pros and cons of using OSS in DER planning and operation will be discussed. Guidance on the adoption of OSS for distribution planning and simulation will be provided. Business benefits will be discussed as well. In addition, this tutorial will introduce example use cases and OSS tools to explore the impact of new loads, controls, and market structures.
