Grids have to deal with input from many distributed, small, and to a large extent heavily fluctuating producers. Additionally, no uniform demand of power
by loads increases the uncertainty of both the power flow and voltage levels that must be supported by the grid. This has two main consequences. First,
it makes controlling and monitoring of every system from a single centralized site unattractive. Second, it demands adaptive management techniques
capable of dealing with changing conditions. The INCIDENT project aims at exploring flexible but also reliable control approaches for efficient and safely
energy transmission and distribution by exploiting Information and Communication Technologies (ICT) to support the shift to distributed generation (DG)
that is taking place thanks to technological innovations, the deregulation process and environmental concerns.
The application domain for the INCIDENT project will be voltage support techniques for renewable DGs. In particular, the project will look at reactive
power control methods to maintain DGs voltages within the admissible voltage ranges in front of varying and dificult transient conditions, without
reducing the production of active power. From a topological point of view, roughly speaking, current practice follow two paradigms, local or centralized
control. Local schemes are based on droop control methods. A peculiar aspect of these methods is that they only have a proportional controller, lacking
any form of integral control. Hence, control of the distributed system is achieved at the price of permitting small errors. Moreover, their effectiveness
holds for smooth transient conditions but they may fail when there is a significant contingency created by severe fluctuation in production and/or
consumption. Alternatively, centralized approaches based on ICT may avoid set-point errors while providing adaptiveness to changing conditions.
However, they imply a central point of failure, and the amount of communication traffic required for massive DG may prevent its application.
The INCIDENT project will explore a third paradigm: distributed/collaborative control. It will imply the deployment of ICT to permit global integrator control
as well as adaptability to unexpected voltage level transients while avoiding the central point of failure and reducing the required network traffic. Several
inter-related topics will have to be accounted for in the development of the novel distributed/collaborative control approaches. The underlying ICT
architecture/technology will determine security properties such as timeliness and fault tolerance as well as adaptability properties such as flexibility and
scalability. In addition, the adopted control triggering paradigm, that is, periodic or event-driven control, will determine deployment costs in terms
communication bandwidth requirements but also will determine flexibility in terms of ability to fast reaction to changing conditions. These issues, together
with the control algorithm itself will allow for an optimized, controlled and secure DG management.
