“…Standard charging methods are used which has two modes of charging, Constant-Current, Constant-Voltage (CC-CV) respectively. These modes are adopted to the control strategy depending on batteries state of charge [17]. In constant current charging mode, the batteries are charged with constant current, while the terminal voltage increases to the desired set point.…”

The management of Renewable Energy Sources (RES) and storage systems in order to connect to an LV distribution network imposes several challenges for the end-user. In addition, the nonlinear nature of the power electronic interfaces and the end-user loads create Power Quality issues in LV distribution network. In this paper, a power electronic device is proposed as a solution to the end-user for the management of RES, storage and for the mitigation of the Power Quality. The device, named Distributed Storage system, is connected in parallel to the end-user and the network. It facilitates online and island mode of operations. The device can manage injection of power into the network, of a RES, such as a PV, charging and discharging of a storage system and mitigate the Power Quality issues of the enduser by acting as a shunt active filter. The system structure, design, and control strategies are dealt with in this paper along with the description of hardware prototype realized.

“…The control for PV and batteries during online or island mode of operation is the same, however, FEC works as a current source during online mode while during island mode, it works as a voltage source. A model-based controller (MBC) is derived to generate duty cycle for FEC [17]. This is common for both online and island mode of operation.…”

“…The storage converter acts as a bidirectional device acting in buck and boost mode of operations for charging and discharging operation respectively, the control in order to control the charging and discharging are realized using simple PI controllers. The detailed modelling of the converter and design of the control for the inverter and the storage converter are described in [19].…”

In order to increase the rate of transformation of traditional grid to a future Smart Grid, there is a huge necessity for enabling the end-user to become an activity participant. Technological and financial considerations are key driving factors in empowering the end-user. From a technological point of view end-user needs to manage his own load, power generated from renewables and also in providing the services to the grid. A promising and innovative solution to meet these needs of the end user in LV network is the Open UPQC (Open Unified Power Quality Conditioner). This device has been designed to meet different tasks required by an end-user (Power Quality, Demand Response, Ancillary Service, etc.). This paper presents the Shunt Unit of Open UPQC with RES (Renewable Energy Sources) as a solution which can provide all the necessary functionalities required by an enduser in enabling him to become an active participant in electrical grid transformation. The performance of the device is demonstrated using simulation results under online and island operation modes.

“…Indeed, DC bus controller is much slower than the 358 main controller in order to avoid oscillation and instability problems in control loop. The DC leg midpoint has been connected through an inductance to the batteries, which, by proper control on up/down switch, will act as a Buck/Boost converter to manage the batteries' charge and discharge working conditions [30]. Shunt unit single phase parameters are listed in TABLE III.…”

“…Each shunt unit consists of a single-phase bidirectional converter connected to an energy storage system and a set of Static Switches (SSs) [30]. There are two different operation modes in function of the main voltage RMS: It can also take over a part of the load and perform peak shaving actions.…”

Power quality in LV distribution networks is already 1 a concern in many European countries especially where there 2 is a strong presence of renewable energy generation. Therefore 3 there is a growing interest in new solutions able to improve the 4 power quality level of such a system. Among them, an interesting 5 solution is represented by the open unified power quality con-6 ditioner (Open UPQC) proposed within the present work. The 7 system consists of a single or three-phase ac/dc power converter 8 installed at customer's premises and a main single or three-phase 9 ac/dc power converter in the MV/LV substation. The paper dis-10 cusses the design, simulation and implementation phases related 11 to an Open UPQC installed in a real LV distribution grid in 12 the city of Brescia (Italy) within the smart domo grid project, 13 co-funded by the Italian Ministry of Economic Development. 14 Results from the field installation show the effectiveness of the 15 proposed solution to face power quality issues in distribution 16 networks.
