Abstract
In recent years the proliferation of renewable energy systems, especially photovoltaic (PV), generating into the low voltage (LV) distribution network has been increasing and these systems are poised to contribute a significant portion of the energy supply. This poses a challenge for maintaining grid stability, which is traditionally reliant on large centralised synchronous machines. For large-scale integration of distributed PV generation, PV systems must be capable of providing grid support services (GSS) emulating the traditional system. This paper presents an accurate, reduced order, computationally inexpensive agent based model (ABM) of a three-phase PV inverter that will provide a platform for analysing advanced control strategies in a multi-agent LV distribution network. The ABM is designed to simulate the actions and interactions of autonomous/decentralised PV systems with GSS for voltage and frequency stability using droop controllers. The developed ABM is validated by comparing results from three independent step changes [Irradiation, frequency & voltage] with a full switching model in MATLAB/ Simscape Power Systems™. These resuts show similar system dynamics and a computational burden reduction of 135:1, hence, providing a simulation agent for large scale integration analysis.
