“…The implemented RPC capability from PVs is depicted in Fig. 4 and has already been used in [12] for studying a real Italian medium voltage network with high penetration of small-size PV plants. The green area between 0.99 U n and 1.01 U n can be interpreted as a dead band with no RPC regardless how the produced active power changes.…”

-With conventional generating units being replaced by renewable sources which are not required to provide same high level of ancillary services, there is an increasing need for additional resources to achieve certain standards regarding frequency and voltage. This paper investigates the potential of incorporating electric vehicles (EVs) in a low voltage distribution network with high penetration of photovoltaic installations (PVs), and focuses on analysing potential voltage support functions from EVs and PVs. In addition, the paper evaluates the benefits that reactive power control may provide with addressing the issues regarding voltage control at the expense of increased loading. Analysed real Danish low voltage network has been modelled in Matlab SimPowerSystems and is based on consumption and PV production data measured individually for number of households.

-Expected deployment of electric vehicles (EVs) introduces big technical challenges for power system operation, but also offers advantages provided that EVs are not considered merely as passive loads. With the development of Vehicle-toGrid technology, EVs will be able to provide a number of ancillary services for grid support, e.g. implemented electronic equipment will allow them to exchange reactive power with the grid for voltage regulation while using active power for other services. This paper investigates the concurrent provision of local and system wide services from EVs in a real Danish low voltage network with high penetration of photovoltaic installations (PVs). The main focus is potential reactive power support when EV provision of frequency regulation coincides with PV production. Furthermore, the paper evaluates benefits of overvoltage support and addresses the issue of increased loading. The analysed network has been modelled in Matlab SimPowerSystems and is based on real hourly metered data from a Danish MV/LV substation with numerous households.

Local distribution networks face voltage-rise problems when numerous distributed generators (DGs) are connected. In particular, voltage rise at low-voltage wires or service wires is a significant because of their high resistance. This paper proposes a methodology for evaluating the installable capacity of DGs under bus-voltage constraints in medium-and low-voltage distribution networks in consideration with power factor control of DGs. Three different installation scenarios for DGs (ideal maximizing DG capacity case, neutral equally maximizing case, and worst minimizing case) are analyzed in medium-and low-voltage networks. Moreover, it is found that the installable capacity of DGs can be increased by using power factor control of inverter-based DGs.
