Application of new generic models for PV and battery storage in system planning studies

Abstract

This paper presents and discusses the application of the new generic dynamic models for renewable plant controls and battery energy storage systems. The plant level control model functions as a master controller that interfaces with devices in a PV generation plant and a battery energy storage system (BESS) both of which function as auxiliary devices. In this paper the generic models for the plant master controller, BESS and PV plant have been configured, parameterized and tuned for use in a system planning study. In this study, both the PV plant and BESS are coordinated and controlled by the plant master controller to maintain a constant net power flow into the grid and to meet system requirements of the renewable interconnection agreement. Dynamic studies show that the configured and parameterized models for the master controller, PV plant and BESS are performing as expected for system contingency events. These tuned models are being submitted to the power system operator for system planning studies and for compliance with the interconnection requirements for the PV/BESS plant. This is the first submission of such generic models configured and parameterized for a combined PV/BESS project. Hence, this paper shares and provides useful guidelines in applying these new generic models of the plant master controller, PV plant and battery storage system for system planning studies on other similar projects.
