摘要

In recent years, small scale renewable generation cells are being rapidly developed and implemented worldwide to supplement traditional energy sources due to challenges to approve new resource development, as well as the attention drawn due to climate change policies. As the price of power increases and to retain the green image of the country, the growth of renewable based distributed generation in New Zealand is predicted to rise. This growth in the near future can change the electricity pattern of New Zealand, impacting the distribution lines business asset structure, revenue, load management and protection, metering, as well as implementing Smart Grid developments. In addition, due to the non linear characteristic of the inverter type equipments, higher penetration of small scale distributed generation devices can cause effects because of the level of harmonic distortion in the network, given the existing recommended standards for distribution generation [1]. Vector as the largest distribution lines company in New Zealand, are planning and closely monitoring the potential impact of penetration of small scaled distributed generation in the network. Given the unique wind and solar radiation profile of the city, independent power quality analysis and device modelling is necessary. Dranetz meters have been installed at the output of the micro wind turbines- in Auckland to collect power quality information since installation of the turbines in 2009. Similar monitoring has been installed at output of a solar photovoltaic plant in Auckland. This paper firstly reviews the modelling techniques for inverter type equipment and thereafter proposes an equivalent technique for inverter type distributed generation device models in ATP software. The compact fluorescent lamp modelling and its impact analysis [2] are reviewed and in this paper we have assessed on similar lines for micro-generation inverter interfaced devices. This paper will then characterise the micro wind turbine and photovoltaic cell using the actual data (current waveform) recorded obtained from power quality measurements. The inverter type models are thereafter assessed and validated using the actual data from a power quality perspective. This paper will also apply high penetration stochastic models on selected Vector distribution network models using DIgSILENT PowerFactory to test the harmonic effect and compare with New Zealand standard and other recommended standards [3]. The inverter type model proposed in this paper will be useful for future distributed generation analysis and impact assessment.
