Disaggregating the Slack Bus: Using Distributed Slack Power Flow for Grid Optimization
Conference Year
2024
Abstract
Power flow studies are ubiquitous in analyzing power systems. Traditionally, the largest generator in a system is designated as the slack bus to manage any mismatch between demand and supply. While this approach is representative of early grid operations, a distributed control scheme has been used since 1949 to assign a proportion of the total mismatch to every generator. Despite this, power flow studies are generally still formulated with a single slack bus. This work explores how the concept of distributed slack employed as a real-time control policy can be used to approximate the solution to optimal power flow problems.
