Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid .
A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and off grid. [2] [3] A stand-alone or isolated microgrid only operates off-the-grid and cannot be connected to a wider electric power system. [4] Very small microgrids are called ...
Vulnerabilities in control systems from a single vendor used at thousands of installations of given source can result in hacking and remotely disabling all these sources by a single attacker, thus largely reversing the benefits of decentralised generation, which has been demonstrated in practice in case of solar power inverters [18] [19] and wind power control systems. [20]
Conversely, when the grid is heavily loaded, the frequency naturally slows, and governors adjust their generators so that more power is output (droop speed control). When generators have identical droop speed control settings it ensures that multiple parallel generators with the same settings share load in proportion to their rating.
A decentralised system in systems theory is a system in which lower level components operate on local information to accomplish global goals. The global pattern of behaviour is an emergent property of dynamical mechanisms that act upon local components, such as indirect communication, rather than the result of a central ordering influence of a ...
Voltage droop is the intentional loss in output voltage from a device as it drives a load. Adding droop in a voltage regulation circuit increases the headroom for load transients . All electrical systems have some amount of resistance between the regulator output and the load.
Autonomous decentralized systems have a number of applications including industrial production lines, railway signalling [1] and robotics. The ADS has been recently expanded from control applications to service application and embedded systems, thus autonomous decentralized service systems and autonomous decentralized device systems.

A mini-grid is an aggregation of electrical loads and one or more energy sources operating as a single system providing electricity and possibly heat, isolated from a main power grid. A modern mini-grid may include renewable- and fossil fuel-based power generation, energy storage, and load control.
