Operation Optimization of Micro-Grid with Electro-Thermal Combined System

In the current environment of rapid development of energy Internet and increasingly close connection between electricity and heat, an operation optimization model of regional grid-connected microgrid based on joint dispatching of electricity and heat is proposed. Considering the characteristics of energy storage in the network, time-of-use electricity price, electric heating load and the timing characteristics of distributed power supply, the grid-connected microgrid including wind turbine, photovoltaic cell, cogeneration system, electric boiler, fuel cell and energy storage system is taken as an example. The simulation example shows that the model can provide reference for energy interconnection and planning operation between electricity and heat.
