In this paper, a genetic algorithm PID controller is designed to control the output voltage of SOFC single battery. The genetic algorithm is adopted and designed to optimize the parameters of standard PID controller KP, KI and KD, so that the difficulties in parameters setting of PID are solved. The simulation results show that the designed genetic algorithm PID controller for the voltage of SOFC single battery can achieve certain and required accuracy as well as fast response speed.

In order to solve the problem of difficult power supply in remote mountainous areas and islands, based on the traditional drooping control of DC microgrid, this paper introduces fuzzy PID to realize the self-adjustment of drooping coefficient, which solves the problem of voltage instability of DC bus caused by external environmental conditions and load mutation. MATLAB/SIMULINK simulation results show that the fuzzy PID droop control can effectively reduce the voltage drop, maintain the bus voltage stability, and realize the current sharing of all distributed power sources in the DC microgrid under the load switching condition.

Abstract. In this current article, it is endeavor to explore the possible methods that are from qualitative to quantitative and also combine computer technology to address social system interaction. A distributed paralleled model based on social computing is established to analyze different experiment data and wish to overcome the limitations of complex systems. At the same time, some simulation results will be illustrated in the follow section to further prove the feasibility of experiment.

The feature-based modeling methods of networks is sharply increasing difficulty with the complication of networks, which usually extremely enhances calculated works of modeling. It leads to the fact that one could not exactly simulates system action. In order to address this problem, a dynamical simulation model that directly form by empiricism is urgently established, which is based on compressed sensing system recognition and prediction.
