And Control

The requirement of system decarbonisation fixed by the EU 2050 plan is leading to an increased establishment of renewable energy sources. Additionally, the emergence of power electronics and ICT technologies has played a decisive role towards a novel distribution electric grid allowing new monitoring, operation and control. In parallel to the energetic transition, an increasing occurrence of extreme weather events and a reinforced concern on climate change leads to the concept of resilience, which is the capacity to adapt and recover from disruptive events in a coordinated procedure. After a fault event, assuming the objective of the system operator is to minimize the load unsupplied, the present study aims at outlining an early research state on the concept of self-healing through the development of a power flow optimization algorithm within a meshed network. Moreover, the effects of integrating Distributed Energy Resources (DER) in order to increase distribution grid resilience as well as to ensure and secure power supply to the system leads to the clusterization of the power system. With controllable technologies, the on-outaged areas are able to disconnect from the main grid, creating islanded microgrids (MGs) which can work autonomously and consequently, increase grid resilience.

Intelligent Planning

The wind-solar-storage and other distributed generation (DG) accessing to the distribution grid and user’s interaction with the grid change the business’s forms of the traditional distribute and utilize system, and while the supplier and demander of electric power also set higher requirements on business’s functions of the smart distribution and utilization system. Based on business requirement of smart distribution and utilization, the major content and function of distribution and utilization link are discussed, including intelligent planning, intelligent dispatching, self-healing control, demand side management, two-way interaction and so on. It makes the architectures of business and the objectives of construction more clear and promotes the construction of the business system in the smart distribution and utilization system.
