Abstract

Although the current regulation of user-side voltage takes into account the needs of users, it mostly adopts rigid regulation, which leads to the increase of carbon emissions in energy consumption of the power grid. In order to improve the above defects and maximize the energy saving of the power grid, a flexible adjustment method for the voltage on the large power user side under the constraint of carbon emission is studied. Through the establishment of user side zip model, the user side voltage flexible control load is analyzed. Taking energy consumption, power factor, three-phase imbalance and time sharing as indicators, the carbon emission constraints of power supply are calculated. Based on the actual demand response of the user side, the hierarchical coordinated control of voltage is realized. In the power grid experiment, the regulation method under the constraint of carbon emission can reduce the carbon emission, and the power energy loss during regulation is reduced by about 3/8 on average, and the practical application effect is better.

碳排放约束下的大用户侧电压柔性调节方法

目前对用户侧电压的调节虽然考虑了用户的需求，但多采用刚性调节，导致电网能耗碳排放增加。为了改善上述缺陷，最大限度地实现电网的节能，研究了碳排放约束下电力大用户侧电压的柔性调节方法。通过建立用户侧zip模型，对用户侧电压柔性控制负荷进行了分析。以能耗、功率因数、三相不平衡和分时为指标，计算供电的碳排放约束。根据用户端的实际需求响应，实现了电压的分层协调控制。在电网实验中，碳排放约束下的调节方法可以减少碳排放，调节过程中的电能损耗平均减少约3/8，实际应用效果较好。
