Gaoya dianqi构网型虚拟同步发电机（GFVSG）可以为电网提供主动支撑，但存在有功频率响应慢和频率抗扰动能力差的问题。文中借助GFVSG参数灵活可调的优势，提出一种基于神经网络的GFVSG多参数协同自适应优化控制策略。首先，建立数学模型，解析转动惯量与阻尼系数对系统的动态影响机理，其次，结合同步发电机功角特性与频率振荡曲线，归纳出参数的动态整定准则与实时需求；最后，引入强非线性映射能力的RBF神经网络，构建参数自整定框架，设计复合误差函数，引入动态耦合系数，实现多参数协同自适应优化控制。仿真结果表明 ...

Gaoya dianqi并网变流器在新能源发电、电能质量治理等领域的应用逐渐广泛，但其输出的并网电流谐波对电力系统有很大影响。重复控制是通过在参考波形中引入谐波成分，并在控制器中将其与误差信号进行比较从而抑制谐波的一种方法，因其对周期性扰动有良好的跟踪性能而在并网变流器中得到广泛应用。但当电网频率波动时，重复控制的谐振频率将会偏离实际电网的基波和谐波频率，大大降低了并网变流器的谐波抑制能力。对此文中提出一种与PI复合应用的多内模自适应重复控制策略来抑制并网变流器中的谐波干扰。首先给出所采用的典型并网变流器拓扑及其控制结构 ...
