This study presents the methodology for the KAPSARC Distribution Hosting Capacity Tool (KDHCT). This tool can support the future of renewable energy in Saudi Arabia. The use of distributed energy resources (DERs), such as solar panels, energy storage and electric vehicles (EVs), is expected to increase. The KDHCT evaluates how many of these assets a particular distribution system can accommodate. The number of DERs and the load that an electric distribution system can reliably accommodate without significant grid upgrades is called its hosting capacity (HC) (Abad, Ma, and Han 2019). HC analysis informs electricity customers and utilities about the best places and times to install DERs and EVs on any distribution system. Thus, utilities can avoid reliability problems and costly distribution system upgrades.
