A dual-module method for energy-internet-oriented distributed energy system planning

The paper provides a kind of energy-internet (EI) oriented distributed energy systems (DES) planning method which is based on the simulation-evaluation and intelligent optimization dual-module planning model to realize optimized configuration of DES. Among them, the simulation evaluation module adopts two-layer bus-structure analysis method. The external bus structure is used to determine the energy flow and equipment power balance equations. The internal bus structure considers detailed network topology and parameters, as well as the special characteristics of electricity and heat network with independent simulation modeling. Through the thermoelectric decoupling iteration method, the dimension and the complexity of the system simulation will be effectively reduced. While the intelligent optimization module constructs a DES optimization problem and solves it through genetic algorithm. This paper improves the extension flexibility of the system optimal planning model with expected accuracy.
