Stable Voltage Waveform and Definition of Grid-Forming In this document, GFM BESS, is referred to as a battery technology equipped with inverters that operates as voltage source synchronised with the grid frequency and inherently provides power to the grid based on the load angle and voltage magnitude.
In fact, it increases the system strength of the nearby power system (e.g. voltage waveform stability), by generating a robust voltage waveform at its own terminal comprising the magnitude and angle at the synchronised 50 Hz frequency.
Collaboration with the Industry The provision of a “stable voltage waveform support service" is new, provided by a relatively novel technology, grid-forming batteries. Transgrid has developed this document based on best available knowledge and information and is now seeking industry engagement to help refine it.
In addition to the Voluntary Specification, Transgrid expects the battery remains grid forming even when operating at the limit; however, it is accepted that the response from battery as a voltage source is only provided up to the current limits.
As analyzed in Sect. 5.2, the larger the equivalent output impedance of the storage-type quasi-Z-source, the smaller its impact on the output power of the system. At the start of the system, the reference output power of the inverter was Pref = 300 W.
The photovoltaic array model used is an Aavid Solar ASMS-180 M. The battery employs an equivalent model consisting of an ideal voltage source in series with an internal resistance. The main parameters of the system are presented in Table 1.
