摘　　要：基于端口能量的附加阻尼控制策略具有控制规律简单、普适性强、物理意义清晰的优点。文中提出了基于实部端口能量的附加阻尼控制策略(R-SDC)和进一步的综合附加阻尼控制策略(CSDC)。与现有的基于虚部端口能量的附加阻尼控制策略(I-SDC)相比,R-SDC更适用于电阻主导的电网,C-SDC可以综合考虑有功功率和无功功率对电压和相角的耦合控制作用,因此在电阻和电抗主导的电网中均优于I-SDC。将基于端口能量的附加阻尼控制策略应用于含光伏发电机的修订的IEEE标准系统,仿真验证了其有效性。The supplementary damping control （SDC） based on port energy is advantageous because of its simplicity, wide applicability and clear physical meanings. The SDC based on the real part of port energy （R-SDC） and the more advanced comprehensive SDC （C SDC） are proposed. Compared with the existing SDC based on the imaginary part of port energy （I- SDC）, the R-SDC is more suitable for resistance dominated networks. As the C-SDC can consider the coupling feature between the active/reactive power and the voltage magnitude/angle, it is better than the I-SDC in both resistance and reactance dominated networks. By applying the control strategies to the solar photovoltaic generators in modified IEEE benchmark systems, the effectiveness of the proposed control strategies is validated.
