[Tianjin Releases Design Guidelines for Near-Zero Carbon Service Areas] The Tianjin Municipal Transportation Commission issued a notice on three highway engineering construction standards, including the "Technical Guidelines for Design and Construction of Near-Zero Carbon Service Areas." The notice mentions that service areas should establish integrated PV-ESS-charging microgrid systems and "PV-ESS-DC-flexible" systems that integrate PV power generation, energy storage, DC power distribution, and flexible power consumption. Energy storage devices should be reasonably configured based on the capacity of the renewable energy power generation system and load conditions to meet the requirements for system stability, energy backup, and improvement of power quality and reliability. The layout of energy storage equipment should adhere to the principles of safety, reliability, and applicability, facilitating installation, operation, maintenance, and handling, while reserving space for future expansion. The layout form should be determined based on the environmental conditions of the highway service area and the performance requirements of the energy storage equipment. Outdoor layout is preferred, and for indoor energy storage facilities, preventive measures should be established to prevent accidents caused by condensation.
