Conflict of instructions on equipments will be caused if the concurrent instructions sent by different systems are different. Based on the background daemon

a new collaboration mechanism of equipment instructions is put forward to handle the conflict of instructions on shared equipment. In this mechanism

the daemon will run according to the goal of each system. What's more

the characteristics of the clean energy system

energy efficiency promotion system and peak-shift system are also considered. This mechanism mainly works in the master station

with the optimization goal and the value of instructions calculated as input parameters. The final instruction is generated via this mechanism while the mechanism based on lock/unlock is introduced to deal with specific scenarios. This mechanism can select the instruction to execute according to its arriving time. The goal to optimize energy utilization and ensure safe operation of shared equipment is achieved by this mechanism

which has been tested and verified in the project of Sino-Singapore Tianjin Eco-city. This work is supported by State Grid Corporation of China.
