Access of plentiful energy routers with power as the core to the distribution network is the future development direction of user-side energy supply. Aiming at the complex structure of energy routers and the inconsistency with the planning goals of distribution network

we propose an integrated planning method for energy routers and distribution network based on multi-agent system coordination mechanism. Firstly

an agent model for energy routers is developed

and the lowest annual cost is taken as an objective function to optimize equipment capacity and planning energy routers. Then

an agent model for distribution network is built

and an improved prim algorithm

combining a control strategy for over-limit voltage and control strategy for over-limit power

is adopted to perform the planning distribution network. Finally

the co-ordination mechanism of multi-agent system is adopted to complete comprehensive planning for energy routers and distribution network. The results verify the effectiveness of the proposed method

the method can be adopted to reduce system planning costs

absorb renewable energy

reduce the peak-valley difference of the tie line

and improve line utilization academic.
