%T Optimal Coordination of PV Active Power Curtailment and EVs Charging among Aggregators
%D 2020
* Multidisciplinary Digital Publishing Institute (MDPI)
%X With the growing adoption of electric vehicles (EVs) and residential photovoltaic (PV)
systems around the world, the distribution system operators (DSOs) are facing several technical
challenges on their network planning and operation, particularly on low-voltage grids. As the
aggregators are intermediary actors at that system level, they are a promising figure to coordinate
these devices in an aggregated manner to help to mitigate adverse effects like overloading of network
assets. However, to do so, proper coordination techniques among these entities and the DSO should
be developed to avoid further investments in new network assets. In this context, a centralised
coordination strategy among aggregators at the DSO level is proposed. By employing a linear
programming model, the optimal export limit of PV and charging profile for each aggregator is
dictated by the DSO, maintaining the operational limits of the network assets. A case study on
two aggregators with moderate and critical penetration levels was carried out. Results show that,
by controlling the aggregated export limit of PV power and the aggregated charging rate of EVs,
high penetration levels can be integrated into current networks with minor or no need for reinforcing
network infrastructure.
