SY] 10 Jul 2026  \nAbstract—Flexible interconnection agreements are increasingly used to streamline the distributed generation interconnection process by limiting real power exports and avoiding costly grid upgrades. Agrivoltaic systems–solar photovoltaic (PV) panels installed over agricultural land–can provide added value under these agreements by adjusting the PV panels away from sun tracking while increasing the sunlight available to crops. This technical note investigates the operation of agrivoltaics under flexible interconnection limits and evaluates their impact on both PV energy production and crop outcomes. We formulate an optimization problem that determines the time-varying tilt of a single-axis tracking agrivoltaic system to maximize energy production subject to a real power export limit over an entire growing season. The resulting PV operating schedules are then used to evaluate PV energy production and crop yield. In a case study, we demonstrate that agrivoltaic systems can comply with flexible interconnection agreements through operational adjustments that improve crop yield, distinguishing them from conventional PV systems that rely solely on inverter curtailment.

INTRODUCTION  \nThe number of distributed energy resources connecting to the power grid is rapidly reshaping power system planning and operation. In 2025, solar photovoltaic (PV) installations accounted for more than half of all new generation capacity added in the U.S. [1] . This rapid growth of distributed generation has placed significant pressure on traditional interconnection processes, which rely on detailed utility studies to ensure that new generation can be safely accommodated (e.g., without violating voltage or thermal limits, or disrupting protection coordination), and to identify any required grid upgrades [2] .  \nTo help address this challenge, many utilities now publish hosting capacity maps to streamline interconnection screening. Hosting capacity represents the amount of distributed generation that can be added to a given portion of the grid without requiring infrastructure upgrades (see [3] for a database of hosting capacity maps). Methods for evaluating hosting capacity remain an active research area. For instance, [4] proposes a stochastic analysis to determine static hosting capacity limits and [5] formulates a dynamic hosting capacity problem which considers fairness in PV curtailment across space and time.  \nIn parallel, flexible interconnection agreements have emerged as a mechanism to enable more distributed generation connections within hosting capacity limits by agreeing to operational constraints such as real power curtailment during specific grid conditions or in coordination with energy storage. For example, the California Public Utilities Commission has enabled renewable energy systems to interconnect under Limited Generation Profiles, which specify a time-varying maximum export amount based on grid conditions [6] .

Emails: hongyiwu, [annastu@mtu.edu](annastu@mtu.edu)  \nthese agreements can reduce interconnection costs for the PV owner by avoiding paying for grid upgrades, there are tradeoffs due to lost energy production from curtailment. However, foragrivoltaic systems, these tradeoffs may be less pronounced, as reductions in grid injections can be achieved through PV panel adjustments that simultaneously support agricultural outcomes.  \nAgrivoltaics involves placing elevated PV panels over agricultural land, allowing the same land to be used for both energy generation and crop production.
