Numbers of incentives were offered by Malaysian government to encourage the growth of renewable energy in meeting the Tenth Malaysian Plan (from 2011 to 2015) target of 98 MW which contributes 5.5% of the total electricity generation.
the rooftop solar PV installation in the LV distribution network imposes potential threats to distribution system operators, as its reversal power flow and reactive power disturbance.
Distribution systems may be considered as a bidirectional system due to the reversing power flow from the excessive connection of PVs, 7 which led to an overvoltage challenge that occurred at the point of common coupling (PCC). 8 Also, the solar irradiance may cause overloading at the components of distribution systems 9; this may lead to an ...
method for radial distribution networks, is proposed. A study based on a highly unbalanced test radial LV distribution network for a typical summer day, with a high µG penetration, is performed. The voltage profile, active power flow in the service transformer, and power losses on the network are the monitored electrical quantities.
The need of electricity is getting increased due to urbanization, increase in population and industrialization. To fulfil the increasing demand, the use of energy generated from solar photovoltaic (SPV) is getting increased and therefore integration of SPV into electricity system is growing substantially. This demands extra electricity from renewable power sources but reason …
This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, effi-ciency, and stability. This paper also introduces the methods that have been
