| 中文摘要: |
| 光伏发电是新型能源体系的重要组成部分,“十四五”期间我国光伏发电装机规模快速增长。光伏发电与天气强相关,随机性和波动性强,高比例光伏并网加大了电力系统平衡难度。通过详细分析高温天气下光伏发电出力特性,指出高温天气下光伏发电具有较高的日间顶峰能力,基于可信容量分析论证了提高极端高温天气下光伏发电参与电力平衡的合理性。最后计算验证了提高极端高温天气下光伏发电可信容量可降低日间电力平衡缺口,给出了光伏参与电力平衡的相关建议。 |
| 英文摘要: |
| Photovoltaic power is an important part of the new energy system, the installed capacity of photovoltaic power is growing rapidly during the 14th Five-Year Plan in China. Photovoltaic power has strong randomness and volatility because of the strong correlation between photovoltaic power and weather, the high proportion of photovoltaic grid- connected increases the difficulty of power balancing in power system. The output characteristics of photovoltaic power under high temperature climate are analyzed in detail, and the view that photovoltaic power generation has a higher daytime peak capacity in high temperature weather is pointed out, and then the rationality of improving the credible capacity of photovoltaic power generation in extreme high temperature weather to participate in power balance is demonstrated. Finally, the calculation verified that increasing the credible capacity of photovoltaic power generation in extreme high temperature weather could reduce the daytime power balance gap, relevant work suggestions about photovoltaic participating in power balance are proposed. |
