  2. Fail2ban - Wikipedia

    en.wikipedia.org/wiki/Fail2ban

    Fail2Ban is an intrusion prevention software framework. Written in the Python programming language, it is designed to prevent brute-force attacks . [ 2 ] It is able to run on POSIX systems that have an interface to a packet-control system or firewall installed locally, such as iptables or TCP Wrapper .

  3. Soft-switching three-level inverter - Wikipedia

    en.wikipedia.org/wiki/Soft-switching_three-level...

    A soft-switching three-level inverter (S3L inverter) is a high-efficiency power electronic inverter intended, in particular, for use with three-phase drives, as a grid-tie inverter for photovoltaic installations or wind turbines and in power supplies. [1] The topology was developed in 2009 at HTWG Konstanz (Constance University of Applied ...

    en.wikipedia.org/wiki/Inverter-based_resource

    An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation ( CIG ), include the variable renewable energy generators (wind, solar) and battery storage power stations ...

  6. Islanding - Wikipedia

    en.wikipedia.org/wiki/Islanding

    Following the 2019 California power shutoffs, there was a rise in interest in the possibility of operating a house's electrical grid as an island.While typical distributed generation systems are too small to power all appliances in a home simultaneously, it is possible for them to manage critical household power needs through traditional load-frequency control.

  7. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.

  8. Variable-frequency drive - Wikipedia

    en.wikipedia.org/wiki/Variable-frequency_drive

    Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

    en.wikipedia.org/wiki/Synchronverter

    Typical control structures for a grid-connected power inverter.(a) When controlled as a voltage supply.(b) When controlled as a current supply. As shown in the figure 3, when the inverter is controlled as a voltage source, it consists of a synchronization unit to synchronize with the grid and a power loop to regulate the real power and reactive ...
