Core Viewpoint - The rapid growth of distributed photovoltaic (PV) installations in rural China, particularly in Shandong province, is facing significant challenges due to the inability of local power grids to absorb the excess electricity generated, leading to the designation of many areas as "red zones" where new projects cannot be connected to the grid [3][5][9]. Group 1: Current Status of Distributed PV in Shandong - Shandong province has the highest installed capacity of distributed PV in China, exceeding 50.2 million kilowatts by the end of 2024, which is equivalent to numerous small green power stations on rooftops and commercial buildings [3][4]. - As of 2024, over one-third of Shandong's counties are classified as "red zones," indicating that the local grid cannot effectively absorb additional distributed PV electricity [5][6]. Group 2: Challenges Faced - The rapid increase in distributed PV capacity has led to a situation where excess electricity generated during peak sunlight hours cannot be utilized, resulting in potential overloads and safety hazards in the power grid [5][6]. - The local power distribution networks, originally designed for unidirectional flow, are now struggling to manage the bidirectional flow of electricity due to the surge in distributed PV installations [5][9]. Group 3: Solutions and Innovations - Solutions to the "red zone" crisis include integrating energy storage systems to store excess electricity generated by PV installations, which can then be released when needed, effectively increasing the grid's capacity to absorb new projects [6][7]. - The establishment of local consumption scenarios, such as community service facilities utilizing PV energy, has shown promise in reducing reliance on the grid and enhancing local energy self-sufficiency [7][8]. Group 4: Future Directions - The development of a new power system ecosystem is essential for addressing the challenges of distributed energy, requiring collaboration among local governments, PV owners, and grid operators to create a market and trading mechanisms for excess electricity [9][10]. - The potential for distributed renewable energy to play a significant role in China's energy structure is substantial, particularly in densely populated areas, but it necessitates a coordinated effort to optimize resource allocation and ensure sustainable development [10][11].

Core Viewpoint - The Gansu Lanzhou Development and Reform Commission has announced the assessment results for distributed photovoltaic (PV) capacity in Lanzhou, indicating that 11 districts will have their distributed PV access suspended due to capacity constraints [1] Group 1: Policy Measures - The document prioritizes the development of distributed PV projects in green zones, while yellow zones require special analysis to ensure consumption conditions are met before development [1] - In red zones, distributed PV access will be suspended until the grid capacity is effectively improved [1] Group 2: Encouragement of Local Consumption - The policy encourages household PV systems to operate on a "self-consumption and surplus electricity online" basis, and commercial PV systems to utilize all generated power for self-consumption, thereby reducing pressure on the public grid [1] Group 3: Capacity Improvement Measures - The document promotes measures such as energy storage configuration and connecting to voltage levels of 10 kV and above to enhance the access capacity for distributed PV [1]
