印度正在加大对可再生能源技术的投资，以满足日益增长的能源需求，水电和其他可再生能源占目前装机容量的三分之一。根据国际能源署的新政策方案，到2035年，风力发电装机容量预计将增加5倍(达到近100千兆瓦)。然而，可再生能源的发电量依赖于当时的气象条件，而气象条件受季风变化的影响很大。繁荣和普遍的电气化正在增加对空调的需求，特别是在温暖的夏天。这项研究使用数十年的观测和气象再分析数据来评估季节内季风变化对印度风电和与温度相关的需求的电力供应平衡的影响。活跃的季风期以印度中部地区的强烈对流和暴雨为特征。这导致气温较低，冷却能源需求较低，而强劲的西风产生了高风力发电量。相比之下，季风期的特点是降雨量受到抑制，气温较高，因此对冷却的需求更大，印度大部分地区的风力发电量较低。在活跃阶段(低需求，高供应)和间歇期(高需求，低供应)期间风电供应和冷却需求之间的对立关系表明，季风变化往往会加剧所谓的需求-净风(即必须由非风源提供的电力需求)的波动。这项研究可能对电力系统的设计和用于维持供需平衡的传统可调度发电设施(如煤炭和天然气)的投资决策具有重要意义。特别是，如果(通常)假设风力发电是作为价格接受者运行的(即，风电场运营商总是希望出售他们的电力，而不管价格如何)，那么传统设施的投资者将面临额外的天气波动，因为季风对生产期的长度和频率(即他们的负荷-持续时间曲线)的影响。
India is increasingly investing in renewable technology to meet rising energy demands, with hydropower and other renewables comprising one-third of current installed capacity. Installed wind-power is projected to increase 5-fold by 2035 (to nearly 100GW) under the International Energy Agency's New Policies scenario. However, renewable electricity generation is dependent upon the prevailing meteorology, which is strongly influenced by monsoon variability. Prosperity and widespread electrification are increasing the demand for air conditioning, especially during the warm summer. This study uses multi-decadal observations and meteorological reanalysis data to assess the impact of intraseasonal monsoon variability on the balance of electricity supply from wind-power and temperature-related demand in India. Active monsoon phases are characterized by vigorous convection and heavy rainfall over central India. This results in lower temperatures giving lower cooling energy demand, while strong westerly winds yield high wind-power output. In contrast, monsoon breaks are characterized by suppressed precipitation, with higher temperatures and hence greater demand for cooling, and lower wind-power output across much of India. The opposing relationship between wind-power supply and cooling demand during active phases (low demand, high supply) and breaks (high demand, low supply) suggests that monsoon variability will tend to exacerbate fluctuations in the so-called demand-net-wind (ie, electrical demand that must be supplied from non-wind sources). This study may have important implications for the design of power systems and for investment decisions in conventional schedulable generation facilities (such as coal and gas) that are used to maintain the supply/demand balance. In particular, if it is assumed (as is common) that the generated wind-power operates as a price-taker (ie, wind farm operators always wish to sell their power, irrespective of price) then investors in conventional facilities will face additional weather-volatility through the monsoonal impact on the length and frequency of production periods (ie their load-duration curves).
