IEC TS 63156:2021描述了光伏系统中使用的独立或并网电力转换设备（PCE）的能量转换性能评估程序。该程序包括计算逆变器性能，以预测光伏系统的发电量。该评估方法基于IEC 61683和IEC 62891中PCE的标准能效计算程序，但提供了额外的方法，用于评估给定太阳能负载曲线的特定位置的预期总体能效。本文件可用作IEC TS 61724-3中PCE的能量评估方法，该方法定义了评估光伏系统相对于其模型或预期性能的实际能量生产的程序。

IEC TS 63156:2021 describes the procedure for evaluating the energy conversion performance of stand-alone or grid-connected power conversion equipment (PCE) used in PV systems. This procedure includes the calculation of inverter performance to anticipate the energy yield of PV systems. This evaluation method is based on standard power efficiency calculation procedures for PCE found in IEC 61683 and IEC 62891, but provides additional methods for evaluating the expected overall energy efficiency for a particular location given solar load profiles. This document can be used as the energy evaluation method for PCE in IEC TS 61724-3, which defines a procedure for evaluating a PV system’s actual energy production relative to its modeled or expected performance.
