吾之电网,其韧若何?
2026-05-24 · via The Hindu: Latest News today from India and the World, Breaking news, Top Headlines and Trending News Videos.

戊申之日(丙申年四月廿二),电政部言,电需破曩昔之极,周四(丙申年四月廿一)峰需近二百七十一吉瓦。政府称此极需得应,示为印度电力之强。然国中多地断电之报不绝。虽言备豫,部亦劝民节用。

据 Grid-India 所报,周五(2026年5月22日)印度电力缺口之巨,约达1.7吉瓦。此情或致部分区域断电。

然实则亏空或更高,多未上报,有专家言。今之监控数据采集系统(SCADA),可察需,助调度中心调电,以维电网之稳,防大范围停电。查南布蒂兰(Chennai)之公民消费者与公民行动集团(Citizen consumer and civic Action Group)电力治理团队领队维施努·劳(Vishnu Rao)言,调度中心宏观运作,地方停电及削减之需,常不载于官方之数。

区域或可由独立于省调中心、各自为政之配售公司故意割裂,致此被压制之需求永无记录,其言如是。又曰,"此等地方性之扰乱或可广布,然仍隐于公众视域之外。"——维什努·劳氏补充。

Deepak Krishnan,WRI印度能源项目副总监也疑之,疑电力分销者犹在显著压制需求,且引Grid-India所报误差幅度为证,示前所未有之热应力影响电力需求。此误差之百分数,表需求预测与实际需求之偏差。近日一日,前日预测误差为4%,实时(短期)预测误差略逾1%。印度总峰值需求,约等于其热电与水电厂之装机容量,能供稳定电力。纸面观之,此示发电容量充裕。情状与美利坚无异,其峰值需求亦近热电、水电及核电之容量。然其地断电之事,极为罕见。

有专家言及配售之弊。K.阿肖克·拉奥,印度电力工程师协会之护法,谓配售之基设未随需求骤增而进步。彼云,将盈利配售之段私有化,致国有电力公司衰微,其本已财困,盖因大半消费者无力承担高费率,致公司所余无几,无以为增基设之资。

时, Uttar Pradesh 之地,电断之患,民甚忧之。 Bengaluru 近数周,电亦频断,时且久。虽省之配电商称系于修整、变压器跳闸及天时之故,然 HRBR Layout、Chandapura、Whitefield 诸地居人言,数时之久,断电已成常事。其处或定时而修,自辰至酉,然不期之断,电压之变,更添民之愠。

Kerala 之境,四月困顿。当其时,电力骤断,时短不过三十分钟,尤在盛时。今月,夏雨骤降,需求稍减,情势稍缓。是邦发电之能,仅其三成,多赖水力,余则购于他处,以应夜半之盛需。

于泰米尔纳德邦,四月之需用电,较五月为高,部分赖短期购电以应之。虽官方裁电之数犹为零,然邦电力部门高官亦承认,地方供电之阻,已及钦奈之部分。

克里希南先生说,区域限电之外,尚有数事隐于其后。其言曰:纵使天下电网图绘一体,然输电之阻,或可阻丰余之电,不得流于匮乏之地;复次,地方电网之限,或基建之弱,亦为患也。

阿什奧克·拉奧先生復言,再生能源之變動,亦為一大難題。彼謂,再生能源之發電者,於電網穩定無責任,而負擔悉歸電網管理者。云「突來之雲翳,可令大半太陽能失於電網,此非可持續之道也。」今印度電力發電,再生能源占其十七,而熱力發電占七十二,水力發電占九,核能發電占二。

或有谓先进之预测技术可助再生电力更有效融入电网。此技术已成功应用于德国等再生能源渗透率颇高之邦。

WRI 之克里希南先生言:峰值之需,适逢太阳能衰微之时;而晚间断电,非可归咎于太阳能之不稳也。
