Voltage Control By Smart Sustainable Buildings: Data-Driven Vs Opf-Based Techniques
The concept of smart sustainable buildings (SSBs) is an important part of the smart city. It includes a variety of controllable devices that provide flexibility to the grid and support its sustainable development. The best way to control these buildings is an undertreated question, with some going for centralized model-based approaches and others opting for local control schemes derived from data. In this paper, through AC-Optimal Power Flow (OPF) modeling of the distribution network, the optimal solution of each controllable equipment is obtained based on historical data. Next, we use machine learning algorithms to design data-driven local control schemes for each controllable device, which can approximate the optimal solution of AC-OPF. Then, the control scheme is applied to specific cases to verify its feasibility and viability as compared to the traditional OPF control scheme, which is popular within the research community. This scheme can promote the safe operation of distribution networks with higher penetration rate (30% to 50%) of controllable devices.
