Abstract:
Being an indispensable carrier of energy Internet,micro-energy network plays an important role in realizing the coordination and optimization of various energy sources as well as the cascade operation of energy. In purpose of maximizing the consumption of renewable energy,improving the utilization rate of energy and reducing the waste of resources,this paper proposes a micro-energy network model including renewable energy that is from wind and light,micro gas units. Power to gas P2G and various energy-storage equipment. Power of users’ platform and thermoflexible loads will be accepted into the requirement-side response resources at the basis of this,this paper constructs day-ahead schedule model under island of energy network in the purpose-function of Minimum cost for comprehensive operation of micro energy grid,and solve the model with the CPLEX solver. Finally,this paper brings into evaluation index functions from the energy side and the load side,carrying out quantitative evaluation of schedule results in different scenarios,and turns out that the micro-energy network system including P2G and micro-gas units under requirement-response can achieve efficient utilization of energy,save operation cost and improve the reliability of power supply under the island.
