Synergy planning for integrated energy stations and pipe networks based on station network interactions

Abstract

Focusing on the problem of failing to consider the load complementary characteristics in the process of dividing the energy supply range for energy stations, this paper proposes an integrated energy station and pipe network synergy planning method that considers load complementary characteristics to achieve alternate optimization for station sites and pipe networks. First, analyses are performed on the interactive relationships between energy station sites and pipe network layouts, proposing an alternate optimization architecture for energy station sites and pipe network layouts. Besides, based on the initial site location and number of energy stations, the division method for energy supply ranges of energy stations is proposed to consider load complementary characteristics. Again, based on the results from energy supply range divisions, a pipe network layout method that considers road information and load access direction optimization is proposed. Then, an optimization method for energy station sites based on load energy distances is proposed. The rationality and effectiveness of the methods in this paper in the energy station site planning, energy station equipment configuration and pipe network layout are verified by cases.
