1.1導(dǎo)言本報告解決了以下問題：“如何準(zhǔn)備國家電力系統(tǒng)連接古吉拉特邦和泰米爾納德邦的海上風(fēng)電項(xiàng)目”針對這一多方面的問題，本報告的結(jié)構(gòu)分為以下小節(jié)和子目標(biāo)：1。政策和行業(yè)背景-為報告提供背景，并概述制定建議的環(huán)境。2。陸上電網(wǎng)開發(fā)-解決為整合古吉拉特邦和泰米爾納德邦的海上風(fēng)電項(xiàng)目而準(zhǔn)備實(shí)際陸上電網(wǎng)所需的步驟。三。海上電網(wǎng)開發(fā)-考慮促進(jìn)古吉拉特邦和泰米爾納德邦海上風(fēng)電項(xiàng)目整合的（新）海上電網(wǎng)開發(fā)所需的條件。四。系統(tǒng)運(yùn)行-評估有關(guān)國家將如何確保穩(wěn)定的系統(tǒng)運(yùn)行，增加海上風(fēng)能和其他可再生能源（RES）的滲透。5個。技術(shù)和法規(guī)代碼-審查現(xiàn)有的一套最相關(guān)的代碼，以確保它們適合開發(fā)海上風(fēng)力發(fā)電項(xiàng)目。1.2背景印度可再生能源的增長受到對當(dāng)?shù)乜諝馕廴?、國際氣候承諾、能源安全需求和可再生能源價格下跌的擔(dān)憂的推動。2007年至2016年，并網(wǎng)可再生能源的復(fù)合年增長率（CAGR）為21.8%。然而，海上風(fēng)電仍然是一種重要的未開發(fā)資源，可以為印度電力進(jìn)一步脫碳做出重要貢獻(xiàn)。海上風(fēng)電項(xiàng)目不面臨土地收購的問題，與陸上風(fēng)電相比，海上風(fēng)電項(xiàng)目通常具有更高的容量因數(shù)，與太陽能光伏發(fā)電具有協(xié)同效應(yīng)。1.3陸上電網(wǎng)開發(fā)及時開發(fā)足夠的陸上輸電基礎(chǔ)設(shè)施對于連接海上風(fēng)力發(fā)電機(jī)和從海上撤離電力至關(guān)重要。在州內(nèi)和州際兩級審查電網(wǎng)發(fā)展情況，以評估電力系統(tǒng)通過州內(nèi)系統(tǒng)將海上風(fēng)電疏散至州內(nèi)各需求中心和州外其他需求中心的能力。本報告進(jìn)一步調(diào)查了古吉拉特邦和泰米爾納德邦綠色能源走廊（GEC）項(xiàng)目的相關(guān)性及其對進(jìn)一步可再生能源整合，特別是海上風(fēng)電整合的重要性。古吉拉特邦能源傳輸有限公司（GETCO）和泰米爾納德邦發(fā)電和配電有限公司（TANGEDCO）分別于2021-22年對古吉拉特邦和泰米爾納德邦的500兆瓦海上風(fēng)電進(jìn)行了電力疏散研究。這些研究結(jié)果表明，陸上電網(wǎng)基礎(chǔ)設(shè)施應(yīng)足以疏散海上風(fēng)電大部分時間。GETCO研究報告中指出的一個問題是，在需求大幅下降的非高峰條件下，海上風(fēng)力發(fā)電削減是必要的。在這種情況下，電力應(yīng)通過各種國家間輸電走廊輸出到國家以外。另一方面，TANGEDCO的研究強(qiáng)調(diào)了及時開發(fā)陸上電網(wǎng)的要求，以確保陸上電網(wǎng)連接和擬議海上風(fēng)力發(fā)電的電力疏散。

1.1 Introduction This report addresses the following question: “How to prepare the state power systems to connect offshore wind projects in Gujarat and Tamil Nadu” In response to this multi-faceted question, the report has been structured in the following subsections  and sub-objectives: 1. Policy and Industry Background - To provide context to the report, and outline the  environment under which the recommendations have been developed. 2. Onshore Grid Development - To address the steps necessary to prepare the physical onshore  grid for integration of offshore wind projects in Gujarat and Tamil Nadu. 3. Offshore Grid Development - To consider what is required to facilitate (new) offshore grid  development for the integration of offshore wind projects in Gujarat and Tamil Nadu. 4. System Operation - To evaluate how the states in question will ensure stable system operation  with increasing penetration of offshore wind and other Renewable Energy Sources (RES). 5. Technical and Regulatory Codes - To review the existing suite of the most relevant codes to  ensure that they are suitable for development of offshore wind projects. 1.2 Background The growth of renewables in India has been driven by concerns over local air pollution, international  climate commitments, need for energy security and the falling prices of RES. From 2007 to 2016 gridconnected Renewable Energy Sources (RES) had a Compound Annual Growth Rate (CAGR) of 21.8%.  However, offshore wind remains an important untapped resource that can make an important  contribution to further decarbonising India’s electricity. Offshore wind projects do not face the issues around land acquisition, typically deliver higher capacity factors compared to onshore wind are  synergistic with solar PV generation.  1.3 Onshore Grid Development The timely development of adequate onshore transmission infrastructure is essential for connection of  offshore wind generators and power evacuation from them. The grid developments are reviewed in intrastate and inter-state level to assess the capability of the power system to evacuate offshore wind power  to various demand centres within the state via its intra-state system and to other demand centres  outside the state. This report further investigates the relevance of the Green Energy Corridor (GEC)  project and its importance to further renewable integration, especially offshore wind integration, in  Gujarat and Tamil Nadu.  Gujarat Energy Transmission Corporation Limited (GETCO) and Tamil Nadu Generation and Distribution  Corporation Limited (TANGEDCO) conducted power evacuation studies for integrating 500 MW of  offshore wind in Gujarat and Tamil Nadu respectively by 2021-22. These study results indicate that the  onshore grid infrastructure shall be adequate to evacuate offshore wind power most of the time. One of  the concerns indicated in GETCO study is that offshore wind generation curtailment shall be necessary in  off-peak conditions when the demand falls substantially. Under such circumstances, the power shall be  exported outside the state via various inter-state transmission corridors. On the other hand, the TANGEDCO study emphasises the requirement of timely onshore grid development to secure onshore  grid connectivity and power evacuation for the proposed offshore wind generation.
