Abstract: To deal with the heavy operational expenditures of the fifth-generation (5G) telecom service providers (TSPs), powering 5G base stations (BSs) with renewable energy (RE) and stimulating a good interaction between the RE-BS and the smart grid is recognized as an effective and practical solution. However, the existing researches on the interaction between RE-BSs and the smart grid mainly study from the perspective of the TSPs, ignoring the operational constraints of the grid. On the other hand, with the rapid development of integrated energy systems, the integrated operation of the power and water distribution system attracts growing attention. And recently, water-cooling has been introduced as a promising energy-saving technique for 5G-BSs, but few efforts have been spent investigating the interaction between the BSs, the power, and the water distribution system. This paper considers the water-cooled 5G-RE-BSs enabled by an integrated electricity-water distribution system (IEWDS), which is managed by the integrated electricity-water service provider (IEWSP). Coordination mechanisms between the TSP and the IEWSP are investigated, and the optimal model with two coordinated operation modes of the IEWDS, incorporating operation constraints of both the IEWDS and the 5G-BS, is proposed. Case studies on two IEWDS sample systems validated the benefits of coordination and the effectiveness of the proposed coordination methods.
