随着对传统电网的安全稳定性提出更高要求，能源危机和环境污染问题日益加剧，“绿色”“低碳”成为电力系统发展的迫切需求，基于此现状提出一种含有电能质量治理的多功能光伏并网逆变器。根据改进自适应谐波检测法检测出并网电流中的谐波分量，随后通过准比例谐振对指令电流进行跟踪控制。通过主客观CRITIC（criteria importance through intercriteria correlation）博弈论组合赋权法，建立电能质量综合评估模型，对谐波分量、无功分量进行综合评估，然后考虑到实际中逆变器容量有限的情况下，构建容量匹配系数，对突出问题进行重点补偿。最后，通过仿真验证并网逆变器在并网过程中对谐波分量和无功分量进行优化补偿，改善了并网点的电能质量，大大提高了逆变器的利用率。因此，验证了所提策略的有效性和可行性。

With the higher requirements for the safety and stability of traditional power grids, the energy crisis and environmental pollution problems are increasing. As a result, “Green” and “Low carbon” have become the urgent needs of the development of power systems. Based on the current situation, a multi-functional photovoltaic grid-connected inverter with power quality control is proposed. First, according to an improved adaptive harmonic detection method, the harmonic component in the grid-connected current is detected. Second, the command current is tracked and controlled by quasi-proportional resonance. Through the subjective and objective criteria importance through intercriteria correlation (CRITIC) game theory combination weighting method, a comprehensive evaluation model of power quality is established to evaluate the harmonic and reactive components. Third, considering the limited capacity of the inverter in practice, a capacity matching coefficient is formulated to compensate the dominating problems. Finally, simulation results show that the harmonic and reactive components are optimized and compensated in the grid-connection process of the inverter, which improves the power quality at the grid-connected point and greatly increases the utilization rate of the inverter. Therefore, the effectiveness and feasibility of the proposed strategy are verified.
