- Losses Minimization
The purpose of the losses minimization is to reduce active power losses in the electrical grid. This control reduces cost of losses for the DSOs in the distribution grid. Novelty of the loss minimization algorithm is that it has a low computational cost, to allow its implementation on lower voltage levels. In the same time, the loss minimization exploits the flexible assets in the grid.
- Energy Balancing
Energy balancing is an operational tool implemented using the hierarchical structure of the SmartC2Net project. The medium voltage grid controller, when receiving a set-point from external systems (for example the TSO) can use both producers and consumers in the medium voltage grid to follow the energy setpoint. Also, a reference can be set to the low voltage grid controller, which subsequently can exploit production and consumption in the low voltage grid to track the reference. Thus, the functionality energy balancing is implemented in both medium and low voltage grid controllers. The controllers implementing the energy balancing functionality get inputs from the assets such as produced energy, available energy and flexibility (up and down) of each asset.
- Demand Management
Flexibility information is associated to loads with thermal and electric storage and consists of maximum and minimum energy values estimated for a future time horizon (hours). These values can be aggregated on household, charging station and even LV grid level and are reported to corresponding Demand Response System. Based on this information, the latter can define a control strategy that is feasible in the sense that it can be enforced. The strategy will target cost minimization, while setpoint following and maximization of local production can be secondary objectives. The Demand Response system is able to perform direct load control and send set-points according to the available flexibility and the control strategy chosen. This system is able to be operated by DSOs or third parties and is flexible, scalable and based on OpenADR2.0b standard.
- Voltage Control (Power Quality Management)
The purpose of the voltage control is to ensure that the voltages along all feeders in an electrical network are within bounds. We consider both the low voltage and medium voltage grids. To facilitate the voltage control, we utilize the existing flexible assets in the grid. The designed control algorithm are resilient towards the unreliable communication between the assets and the controllers, and the time-varying and uncertain flexibility of the assets. The overall aim is to maximize the utilization of renewable resources while satisfying grid constraints.
