Research on Multi-Microgrids Scheduling Strategy Considering Dynamic Electricity Price Based on Blockchain

In order to improve the economy and safety of multi-microgrids (MMGs) scheduling, this paper proposes a research on MMGs scheduling strategy that takes into account dynamic electricity prices based blockchain. We first introduce principle blockchain, analyze security combination blockchain design architecture process platform. Second, we set price model according total power supply demand MMGs, load optimization model. Finally, take optimal system minimum environmental pollution as objective function, then use linear programming method improved krill herd algorithm (KHA) with nonlinear changes in weights solve problem. The simulation results show that: (1) can reflect microgrids optimize load; (2) Comparing three schemes, economic protection by 37.33% 39.34%, while reduce interactive between microgrid distribution network 56.28%, curtailment rate 63.22%; (3) has higher convergence speed accuracy;(4) technology ensure data.
