“…As outlined in the introduction ELECTRA IRP targets a cell-based control approach (i.e., WoC) where various observable and control functions are being developed [6]. Within the scope of the project, the concept of the PPVC voltage control has been proposed [22]. The main idea under investigation is the possibility of defining "Cells" within a distribution network, each with its own PPVC controller that works independently.…”

Renewables are key enablers for the realization of a sustainable energy supply but grid operators and energy utilities have to mange their intermittent behavior and limited storage capabilities by ensuring the security of supply and power quality. Advanced control approaches, automation concepts, and communication technologies have the potential to address these challenges by providing new intelligent solutions and products. However, the validation of certain aspects of such smart grid systems, especially advanced control and automation concepts is still a challenge. The main aim of this work therefore is to introduce a hardware-in-the-loop co-simulation-based validation framework which allows the simulation of large-scale power networks and control solutions together with real-world components. The application of this concept to a selected voltage control example shows its applicability.

The concept and experimental validation process of the Web-of-Cells (WoC) based Post-Primary Voltage Control (PPVC) developed in EU FP7 project ELECTRA IRP is presented in this paper. The main objective of PPVC is to provide an optimal and local voltage control replacing the conventional secondary and tertiary voltage control. The Power Hardware-In-the-Loop (PHIL) setup and the experimental results comparing the PPVC approach to traditional voltage control techniques are presented and discussed. The PPVC has demonstrated lower number of tapchanges and faster response to topology changes. To avoid simulation overrun in real-time environment, a slower simulation step is adopted for the electrical network model than the converter and grid emulator controller models in the Simulink model. The PHIL test conducted gives insight to the potential obstacles that may arise with increased number of cells and increased number of nodes in the network.

“…The PPVC [19] restores the voltages in the nodes of the cell to the set point values while minimizing the power losses in the cell. It ensures the balance between reactive power flow optimization and robust voltage set-points (within a tolerance band) that do not trigger a new set-point calculation continuously if the set-points are close to the safe band limits.…”

“…As the PVC is an automatic control with no real involvement of the cell operator, this paper is dedicated to the visualization and control of the PPVC resources done by the cell operator from the control room. The PPVC [19] restores the voltages in the nodes of the cell to the set point values while minimizing the power losses in the cell. It ensures the balance between reactive power flow optimization and robust voltage set-points (within a tolerance band) that do not trigger a new setpoint calculation continuously if the set-points are close to the safe band limits.…”

“…In practice, nowadays the implementation of a centralized OPF is still troublesome [3,20]. However, the PPVC could be possible in the 2030+ horizon where ELECTRA IRP focuses, thanks to the advances in grid observability and the rise of the calculation capacities, the communication systems and the data processing algorithms that are constitutive of the WoC [19].…”

Abstract:In future power grids, a large integration of renewable energy sources is foreseen, which will impose serious technical challenges to system operators. To mitigate some of the problems that renewable energy sources may bring, new voltage and frequency control strategies must be developed. Given the expected evolution of technologies and information systems, these new strategies will benefit from increasing system observability and resources controllability, enabling a more efficient grid operation. The ELECTRA IRP project addressed the new challenges that future power systems will face and developed new grid management and control functionalities to overcome the identified problems. This work, implemented in the framework of ELECTRA, presents an innovative functionality for the control room of the cell operator and its application in assistance with the voltage control designed for the Web-of-Cells. The voltage control method developed uses a proactive mode to calculate the set-points to be sent to the flexible resources, each minute, for a following 15-min period. This way, the voltage control method developed is able to mitigate voltage problems that may occur, while, at the same time, contributes to reduce the energy losses. To enable a straightforward utilization of this functionality, a user interface was created for system operators so they can observe the network state and control resources in a forthright manner accordingly.
