Claim 0:
1. An add-on renewable power plant (ARPP) comprising:
a renewable energy source (RES) connected to a legacy renewable power plant (LRPP) interconnection infrastructure, wherein an output capacity of the RES is sized based on an LRPP interconnection infrastructure transmission capacity and an LRPP power output profile, the LRPP interconnection infrastructure transmission capacity indicating a maximum amount of energy that can be transmitted from the LRPP to a grid;
an energy storage system (ESS) connected to the LRPP interconnection infrastructure, wherein a storage capacity of the ESS is sized based on the LRPP interconnection infrastructure transmission capacity and the LRPP power output profile; and
an ARPP controller operatively coupled to an RES inverter coupled to the RES and a bidirectional ESS inverter coupled to the ESS, the ARPP controller configured to:
receive an indication of an LRPP power output from an LRPP controller, wherein the LRPP controller adjusts inverter setpoints for an LRPP RES independent of the ARPP controller;
calculate a difference based on the LRPP infrastructure transmission capacity and the indication of the LRPP power output; and
responsive to the received indication of the LRPP power output, directly adjust an RES inverter setpoint of the RES inverter and directly adjust an ESS inverter setpoint of the bidirectional ESS inverter, wherein the RES inverter setpoint and the ESS inverter setpoint are selected to direct, from the RES inverter and the ESS inverter, power substantially equal to the calculated difference to the grid.
