零碳园区怎么建？绿电直连/源网荷储/新型储能给出实践方案

Core Viewpoint - The establishment of the first batch of national zero-carbon parks marks a significant shift from local exploration to a systematic national project aimed at achieving zero-carbon goals, with energy system transformation and high integration of renewable energy being central to this initiative [2][6]. Group 1: National Zero-Carbon Park Construction - The first batch of national zero-carbon parks includes 52 parks, with construction deadlines set for 2027 to 2030 [2]. - The distribution of parks varies by region, with some provinces like Chongqing, Zhejiang, and Tibet having one park, while others like Xinjiang and Jilin have three [2]. - The transition to zero-carbon parks emphasizes the need for energy system transformation and the integration of renewable energy, highlighting the critical role of energy storage as a regulatory resource [2][11]. Group 2: Policy Evolution - The development of low-carbon parks in China has evolved through several stages, including ecological parks, low-carbon parks, near-zero carbon parks, and now zero-carbon parks [3][4]. - The "13th Five-Year Plan" period saw the formal inclusion of carbon emission intensity in national assessments, while the "14th Five-Year Plan" marks the transition of zero-carbon park construction from pilot projects to a national strategy [6] [10]. Group 3: Key Tasks for Zero-Carbon Parks - Eight key tasks have been identified for the construction of zero-carbon parks, including energy structure transformation, energy efficiency improvement, industrial structure adjustment, resource recycling, infrastructure upgrades, technology innovation, energy and carbon management enhancement, and support for reform and innovation [7]. Group 4: Energy Storage Requirements - Various regions have set energy storage requirements for zero-carbon parks, with some provinces like Shanghai requiring a storage system configuration ratio of 15% to 30% [9]. - Other provinces, such as Jiangsu and Sichuan, have established specific metrics for new energy storage capacity relative to average daily electricity consumption [9][10]. Group 5: Green Electricity Supply and Storage Integration - The construction of zero-carbon parks necessitates a collaborative approach to carbon reduction, with a focus on increasing the use of clean energy through high proportions of non-fossil energy [11][13]. - Policies have been introduced to facilitate the direct supply of green electricity and the integration of source-network-load-storage systems, allowing for a more efficient energy consumption model [14][15]. Group 6: New Energy Storage Opportunities - The potential for new energy storage applications is significant, particularly in high-energy-consuming industries, with provinces like Shandong and Inner Mongolia showing high electricity consumption in these sectors [17][20]. - The integration of energy storage solutions is essential for ensuring the stability and flexibility of the energy system, enabling the effective consumption of renewable energy [23][27]. Group 7: Case Studies - Notable examples of zero-carbon parks include the Ordos Zero Carbon Industrial Park, which utilizes 80% of its energy from wind and solar sources, and the Beijing JinFeng Technology Park, which has achieved renewable energy "carbon neutrality" [24][25][26]. - These case studies illustrate the successful implementation of integrated energy systems that combine various renewable sources and storage technologies to achieve sustainability goals [24][25][26].
