Energy transition on power systems is driven by decarbonization, decentralization and digitalization. At distribution networks, such
evolution is provoking a shift towards smart grids, which must facilitate at the same time that consumers have to be at the core of power
system operation.
The deployment of the smart grids has been led by distributed generation based on renewables sources which is being connected to lower
voltage levels, including within consumer facilities.
However, renewable generation has a stochastic behaviour and do not often match with consumers demand, which presents an stochastic
behaviour, too. These also affects both distribution system operator (DSO) and retailer/balance responsible party (BRP).
In order to manage the variability of such renewable-based distributed generation, and optimize the use of infrastructure and portfolios of
retailer/BRP, it can be considered hardware and software solutions for providing such flexibility to power system operation.
Software solutions are based on information and communication technologies, and include demand response strategies through energy
management systems (EMS) at individual level (household) and at community level (aggregated). Hardware solutions are mostly based on
power electronics converters for charging/discharging energy storage systems and electric vehicles, and curtail/control generation and/or
When a set of loads can be supplied with local generation, combined with some storage system, even centralized, dispersed or mobile,
operated according to EMS, permits to obtain a microgrid. A microgrid can be considered at individual level (single consumer) or at
community level (a set of consumers considering either a private network or a public network), as long as there is a single point of common
coupling with the network, and can be connected to such network or can be isolated from it.
Isolated mode introduces new options for flexibility. However, due to its small size, stability in microgrids with large presence of power
electronics converters is key for following EMS setpoints and assuring a proper power quality in isolated mode at the same time.
Therefore, this proposal has 2 main work package (1) energy management optimization of distributed energy resources placed at
consumers microgrids for providing flexibility, and (2) stability issues of microgrids with large presence of power converters. Then, the
expected results will be (A) new optimization algorithms for EMS with renewable generation, electric vehicles, loads and
centralized/dispersed/mobile storage system;(B) new topologies and control strategies of power converters for assuring good dynamics in
microgrids; and finally (C), which are the interactions between the energy management layer and power electronics control layer relative to
stability and in compliance with EMS setpoints.
Both working package, flexibility algorithms and stability in microgrids, will be developed in paralled and will meet in a third work package,
where the experimental platform of CITCEA-UPC centre will be used for testing new developments from the previous work packages.
These developements are expected to be the basis for future projects of technology transference with the industry.
The dissemination of the results will be through publications in conferences and indexed journals.
