The high penetration of distributed photovoltaic generation into distribution networks has become a major development trend in the future. However, the intermittency and random fluctuations of distributed photovoltaic output have exacerbated voltage violation and fluctuation issues in distribution networks. To address this problem, a distribution network zoning voltage coordination control strategy is proposed. In terms of zoning, voltage sensitivity index information obtained from daily power flow calculations is utilized to analyse and express the impact variation of photovoltaic generation on the voltage of each node. Based on the threshold requirements of voltage variation indices, the zoning of nodes is determined. In terms of zoning voltage coordination control, a strategy of voltage sensitivity control within the partition is adopted, pairing nodes within each partition and utilizing the active and reactive regulation capabilities of photovoltaic generation to control all over-limit voltage within normal range. Furthermore, through the interval distributed voltage coordination control strategy, the interval state variables are equivalenced, and based on the SADMM algorithm, the dynamic reactive power compensation amount between adjacent partitions is optimized to achieve the optimization and suppression of network-wide voltage fluctuations. Taking the IEEE 33-node system as an example, a case study was conducted to verify the effectiveness and feasibility of the proposed strategy in practical applications.

This paper presents an innovative approach to optimizing hybrid energy storage systems (HESS) in offshore wind farms, with a particular focus on extending the storage's lifetime. We introduce a novel optimization model that integrates the complexities of offshore wind energy generation with the dynamic characteristics of multiple energy storage technologies. The model aims to maximize the efficiency and reliability of energy storage by effectively balancing the load between different storage units, thereby mitigating the degradation of storage components and prolonging their operational *** results demonstrate that our optimized HESS not only improves the overall performance of offshore wind systems but also significantly reduces the long-term operational and maintenance costs by extending the storage units' lifetime.

With the transformation of global energy structure and the rapid development of intelligent transportation system, the interaction between power grid and vehicle network has become a research hotspot. Especially the popularization of electric vehicles (EVs) and the progress of smart grid technology play a key role in maintaining the stable operation of power grid, optimizing energy distribution and improving the reliability of power system. The purpose of this study is to deeply discuss the frequency control and optimization of auxiliary load in power grid under the background of diversified vehicle-network interaction, and put forward effective control strategies through analysis and research. The research methods include establishing a fusion model of power grid and vehicle network, proposing an auxiliary load control strategy based on vehicle battery and fleet scheduling, and using MATLAB/Simulink for simulation analysis. Through simulation analysis, the effectiveness of the proposed strategy is verified, including adjusting the charging and discharging behavior of EV to stabilize the power grid frequency, optimizing the dispatching plan of bus fleet to improve the power grid frequency stability and so on. It is of great theoretical and practical significance to study the frequency control and optimization of auxiliary load in power grid for diversified vehicle-network interaction. The strategies and methods put forward in this study not only help to improve the stability and efficiency of power grid, but also help to promote the further development of intelligent transportation system and contribute to the realization of energy saving, emission reduction and sustainable development goals.
