Research on Multi-Energy Complementary Ratio of Inner Mongolia Grid Based on Solar Thermal Power

建立了一种风电、光伏以及太阳能热发电多能互补装机配比计算模型及其评价指标。拟定了7种配比方案,并以内蒙古电网夏冬典型日负荷作为优化目标,使用计算模型及其评价指标对各配比方案进行计算分析。结果表明,基于基础参数计算的配比为风电装机150 MW、光伏装机50 MW、太阳能热发电装机100 MW的方案具有更好的电能质量和电网运行稳定性,同时具备更好的系统整体送出能力,可有效减少弃风弃光。

A calculation model and evaluation index of the ratio of wind power,photovoltaic power and solar thermal power were established.Seven matching schemes were worked out,and the typical daily load curve of Inner Mongolia power grid in summer and winter was taken as the optimization objective.The calculation model and its evaluation index were used to calculate and analyze the matching schemes.The results showed that,based on the calculation of basic parameters,the scheme with the ratio of 150 MW for wind power,50 MW for photovoltaic power and 100 MW for solar thermal power had better power quality and grid operation stability.At the same time,the system had better overall delivery capacity,which could effectively reduce the waste of wind and light.
