Summary: This article addresses the issue of uncertainty in the use of new energies by solving the flexibility planning of electric vehicle charging and discharging with the help of the CPLEX solver. It aims to coordinate with wind and solar production and compensate for the uncertainty of these resources. The results show that considering uncertainties can reduce costs through optimal planning for electric vehicles, which is also profitable for the operator.

Summary: This paper focuses on the global optimality of the relaxed solutions of a multi-timescale co-optimization problem. The proposed co-optimization framework involves the multi-timescale co-optimization of distribution feeder reconfiguration with the optimal dispatch of traditional voltage regulating devices and utility-scale distributed energy resources. The optimal switching plan is computed on a daily basis. The proposed multi-timescale co-optimization model is formulated as a mixed-integer second-order cone program to achieve global optimum. The objective is to reduce power losses and improve load balancing. The simulation results demonstrate the feasibility and global optimality of the relaxed solutions computed by the co-optimization framework.

Summary: This paper proposes an optimal power flow (OPF)-based control method for smart inverters (SI), aiming to address voltage violations in distribution networks with a higher penetration of inverter-based generations. By optimizing the power flow, more accurate operating set points can be obtained to regulate the voltage at affected nodes. Compared with sensitivity-based Volt-Var Control (VVC), Volt-Watt Control (VWC), and combined VVC and VWC methods, the proposed OPF-based control optimizes network loss and maintains voltage violations with less reactive power support in a European low-voltage and CIGRE medium-voltage distribution network.

Summary: This paper investigates the use of a drone equipped with simultaneous transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS-UAV) for wireless communications in multi-user networks. The energy splitting and mode switching protocols are used to control the reflection and transmission coefficients, and the beamforming vectors as well as the coefficient matrices are optimized to maximize the sum rate of the system. Simulation results show that the STAR-RIS-UAV-aided CoMP system achieves a higher sum rate compared to conventional RIS systems or systems without RIS. The proposed structure is also more flexible and promotes a higher sum rate.

Summary: This paper investigates the generation mechanism of the 6th order harmonics and high-frequency resonance in PV grid-connected inverters and proposes a method to absorb the resonant component using an active damping approach by constructing a virtual resistor. Additionally, an adaptive modulation voltage compensation method is introduced to reduce the low-order harmonics. The theories are verified through actual measured data and comparative simulations, which demonstrate that the proposed coordinated control algorithm effectively reduces the resonance point peak and mitigates low-order harmonics by more than 50%. The proposed method is applicable to various operating conditions.

Summary: This paper investigates the joint optimization of BS clustering and power control for NOMA-enabled CoMP transmission in dense cellular networks to maximize system sum-rate. A power control algorithm is designed to meet the NOMA decoding condition and users' rate requirements, while a BS clustering algorithm is designed to iteratively update the BS clustering and NOMA user grouping to increase system sum-rate. Simulation results demonstrate that the proposed scheme efficiently alleviates interference among coordinated BSs to improve system sum-rate and spectrum efficiency of NOMA-enabled CoMP transmission even under high user density.
