The paper presents a set of probabilistic functions based on stochastic RES (PV and Wind) forecasting and probabilistic load flow, which use the AMR (Automatic Meter Reading) infrastructure for data acquisition at MY Networks and the SCADA measurements at the MA" bus. More specifically, probabilistic functions are implemented, in order to provide improved monitoring of the system state, identification...
This paper analyses the 11 kV Medium Voltage (MV) networks using real network and load data. High penetration Photovoltaic (PV) connected to a MV feeder is modeled using RETScreen to estimate the output power based on meteorological and geographical data. Simulations are run across 24 hour period to see the voltage fluctuations, active and reactive power behavior, load profile, power loss and energy...
This paper describes a granular approach for investigating the impacts of very high PV generation penetration. Studies on two real-world distribution feeders connected to PV plants are presented. The studies include both steady-state and time series power flow analyses, which include the effects of solar variability. The goal of the study is to predict the effects of increasing levels of PV generation...
Recently, a large number of photovoltaic systems have been installed in the distribution system. Reverse power flow through the distribution line caused by photovoltaic generation results in the voltage deviation from the specified range. Usually, the photovoltaic system is controlled autonomously using an individual power conditioner. Autonomous control causes inequality of the photovoltaic generation...
This paper deals on control strategy and analyzing power flow between home integrated photovoltaic system (PVS), plug-in hybrid electric vehicle (PHEV) and distribution network The neutral point clamp (NPC) multilevel inverter is the main element that allows interfacing between the different energy sources and receptors. The combination of synchronous reference frames (SRF) and indirect control algorithms...
Integrating Photovoltaic (PV) systems with battery energy storage in the distribution network will be essential to allow for continued uptake of domestic PV system installations. With increasing concerns regarding environmental and climate change issues, incorporating sources of renewable energy into power networks across the world will be key for a sustainable future. Australia is well placed to...
Photovoltaic Distributed Generation (PV) is experiencing a growing proliferation prompted by a mixture of favorable legislation, incentives, technology developments and cost reduction. PV installed capacities can vary from a few kW (small-scale) to several MW (large-scale). Due to its intermittent nature, increasing penetration of large-scale PV may lead to potential impacts on planning and operations...
Grid-connected photovoltaic power station has changed the distribution of transmission power, thus influences the voltage distribution of load node. In accordance with the relevant provisions, grid-connected photovoltaic power stations should not be active participation of voltage regulation, but it grid-connected will have a supporting role for each node voltage. This paper proposes a maximum admission...
An IEEE 34 node test feeder is constructed by using DIgSILENTPowerFactory. The load flow results are more or less as given by IEEE. Dynamic and static photovoltaic system, dynamic and static wind generator are modeled. Distributed generators are modeled in the setting in a way, such that load flow calculations can be carried out when they are interfaced to IEEE 34 node test feeders system. Different...
