High PV Penetration Impact on European-based LV Residential Network

Abstract

The impact of high PV penetration into the grid particularly at the distrib ution side has b een extensively studied. However, most of the availab le research focuses on North American style systems. This project aims to investigate the effect of high PV penetration at a residential area in a European-based distrib ution network, which is electricity supply system Malaysia is b ased on. The modeling is done using OpenDSS while the network model used is the IEEE European Low Voltage Test Feeder which consists of 55 loads representing a generic housing area. Each load point is then equipped with a 4 kW PV system-representing a typical size for a house installation. PV output variab ility is then introduced into the modeling using two sample days of actual irradiance variab ility ob tained from UTeM Malaysia; one for clear day and another for a high variab ility day. Voltage unb alance, voltage rise and reverse power flow were analyzed. One significant finding of this project is that voltage rise exceeds the standard of 1.05 pu during noon. Besides that, the high variab ility days significantly affect the mitigation measures required to manage reverse power flow.

Towards energy transition: conjoint assessment of large-scale PV system performance and interconnection impacts in isolated microgrid

“…of the nominal voltage. Dissimilar to the finding in [30] corresponding to a typical grid, no voltage limit violation is reported, albeit the presence of reverse power flow. Moreover, the resulting voltages are far from violating the limits.…”

“…Meanwhile, Nadeem Khan et al [29] argued the significance of considering the variations, which is practiced in our present study. Baharin et al [30] attempted simulating the impact of installing a 4 kWp PV system unequally at each phase of 55 load points in a typical IEEE European power grid. The change in power flow direction and breaching of statutory voltage limit between 10:00 hour and 16:00 hour were discovered.…”

“…On the other hand, on the previous research, the control strategy for distributed integration of photovoltaic (PV) and battery energy storage system in microgrid, reactive power optimization of distributed generation for voltage regulation of distribution systems, and reconfiguration of distribution network with DG using fuzzy multi-objective method has been investigated by [7] [8]. Other than that, high PV penetration impact on European-based low voltage (LV) residential network has been researched by [9]. Besides that, load flowbased voltage strategy indices for voltage stability and contingency analysis for optimal location of Static Synchronous Compensator (STATCOM) in distribution network with the integrated distribution unit has also been investigated by [10].…”
