针对高比例可再生能源并网导致的微电网惯性下降问题,聚焦于虚拟同步发电机控制交流微电网的功率经济分配与数据安全协同优化问题展开研究。首先,提出了一种融合模型预测控制的改进增量成本一致性算法
对功率不平衡值进行计算,打破了传统一致性算法中领导节点需要计算全局信息的限制。其次,提出了一种双维度协同的自触发隐私保护策略,并采用差分隐私机制对交互信息进行噪声注入以解决数据泄露问题。同时,结合事件驱动的自触发机制以减少计算负担并降低通信和加密成本。最后,通过4机7节点系统进行仿真验证。结果表明,所提自触发隐私保护策略显著减少了通信资源与计算资源,提升了微电网控制的鲁棒性与隐私安全性。
Aiming at the problem of reduced inertia in microgrids due to the high proportion of renewable energy integration
this paper focuses on the coordinated optimization of power economic allocation and data security in AC microgrids controlled by virtual synchronous generators. Firstly
an improved incremental cost consistency algorithm integrated with model predictive control is proposed to calculate the power imbalance value
breaking the limitation of traditional consistency algorithms where the leader node needs to calculate global information. Secondly
a two-dimensional coordinated self-triggered privacy protection strategy is proposed
and the differential privacy mechanism is adopted to inject noise into the interaction information to solve the data leakage problem. At the same time
the event-driven self-triggered mechanism is combined to reduce the computational burden and lower communication and encryption costs. Finally
the 4-machine 7-bus system is used for simulation verification. The results show that the proposed self-triggered privacy protection strategy significantly reduces communication and computing resources and enhances the robustness and privacy security of microgrid control.
