Summary

Connection limits define the allowable range of power (in kW) that distributed energy resources

(DER) can import from or export to the distribution grid. These limits are established to prevent potential negative impacts on grid operations. Unlike traditional static connection limits, dynamic limits can be adjusted in real time or near real time based on current or forecasted grid conditions, offering a more efficient and responsive approach to managing DER-grid interactions. This paper explores the implications of dynamic connection limits for distribution utility oversight of DER participation in U.S. wholesale electricity markets. In particular, it assesses whether dynamic connection limits could reduce the need for distribution-level overrides relative to static limits, thereby enhancing both distribution system reliability and wholesale market efficiency.
