The high penetration of photovoltaic (PV) panels in a distribution system could cause sharp fluctuations in bus voltages. This phenomenon could induce abnormal operations in high-precision equipment or result in erroneous computer memory functions. To handle this issue, this paper proposes a voltage control to smooth out a critical bus voltage, without utilizing the local controllable devices, while maintaining the bus voltages across the distribution system within the allowable range. First, a smoothing out control of voltage is proposed and theoretically proved to mitigate the voltage fluctuations at the critical bus by the first-order inertia. Second, an optimization model is proposed for the coordinated voltage control, which coordinates the actions of discrete control devices with the smoothing out control of PV inverters. A novel convex approximation method is proposed to transform the nonconvex model into an approximate convex model. It is theoretically proved that the solutions obtained by solving the approximation model can control the bus voltages across the distribution system within the allowable range. Last, the proposed voltage control is simulated in 15-bus and 51-bus distribution systems. The 6-minute and 24-hour simulations show that a single voltage fluctuation and the sum of squared voltage fluctuations at a critical bus are reduced by 22.4% and 36.5%, respectively, as compared to the results offered by using the existing benchmark control method.

The integration of renewable energy sources (RESs) into active distribution networks (ADNs) is essential for reducing carbon emissions but often results in voltage fluctuations and violations. This paper proposes a hierarchical voltage control framework that effectively coordinates diverse controllable devices with various response times in an ADN. The framework comprises three stages: day-ahead scheduling of on-load tap changer (OLTC), intra-day optimization for droop slopes and references for droop controllers in Soft Open Points (SOPs) and distributed generators (DGs), and real-time local voltage regulation. Unlike existing approaches, the proposed approach analytically establishes voltage stability constraints and incorporates them into droop slope optimization for local controllers, mitigating voltage oscillation risks. Additionally, a novel deviation-aware optimization method is developed to calculate optimal voltage references. This method treats the deviations between fixed-point voltages and their references as uncertainties and accounts for their impacts on voltage security through chance-constrained programming. Simulation results demonstrate the effectiveness of the proposed framework in improving voltage regulation performance with guaranteed stability.
