Voltage support using active distribution networks
Abstract: In transmission networks, voltage regulation has primarily been managed through power plants. Their synchronous generators produce or absorb reactive power to adjust the voltage as needed. However, the rapid phase-out of conventional thermal power plants, driven by commitments such as the Paris Agreement, necessities a paradigm shift in voltage control. This work explores how distribution grids that control their reactive energy exchange, similar to power plants, can actively participate in the voltage support. A centralized and robust OPF-based control scheme is proposed, it uses the flexibility from photovoltaic (PV) plants to achieve a certain power flow at the grid connection point while respecting local grid constraints. A linearized grid model , based on sensitivity coefficients, is used to maintain convexity of the problem. These sensitivity coefficients are recursively estimated using on-line measurements. On going work is to validate the approach through case studies to assess its robustness and effectiveness.
