为了解决我国北方地区风电的弃风问题，改进剩余风电供暖系统的直接消纳储能技术，改善电蓄热供暖控制系统中存在换能装置电热转化效率低下的问题，经过方案对比提出采用电热转换效率高、安全可靠性好的电磁感应加热装置作为供暖系统的换能装置。为优化储能水箱加热供暖系统的控制策略，针对系统给定的控制需求，采取前级附加给定温度模糊控制器串联后级感应加热模糊PID控制器的复合控制策略，使闭环加热系统的给定温度随室外温度的变化而调整；同时为了节约不可再生能源，降低损耗，采用与后级模糊PID控制器的输出构成闭环比值随动控制系统的加热循环流量协调控制策略。利用Matlab/Simulink软件进行仿真实验，结果表明：模糊PID控制特性明显优于传统PID控制，系统的超调量显著减少，动态调节速度明显加快；实现模糊控制和模糊PID控制复合与协调智能控制策略的网络化，提高了系统控制的实时性和可靠性，使系统控制性能大为提升。

In order to solve the problem of wind abandonment for wind power in northern China,improve the energy storage technology of wind power directly absorbed by surplus wind power for heating system and resolve the problem of low electric heating conversion efficiency of energy conversion device exists in the electric regenerative heating control system, through comparison of schemes, the electromagnetic induction heating device with high electric heating conversion efficiency and good safety and reliability is adopted as the energy conversion device of the heating system. In order to optimize the control strategy of the heating system of the energy storage tank, according to the given control requirements of the system, a compound control strategy of the fuzzy controller of the former stage attached with the given temperature and the fuzzy PID controller of the latter stage induction heating in series is adopted, so that the given temperature of the closedloop heating system can be adjusted with the change of the outdoor temperature. At the same time, in order to save nonrenewable energy and reduce consumption, the heating circulation flow coordination control strategy for the closedloop ratio servo control system with the output of the latter stage fuzzy PID controller is adopted. Matlab/Simulink software is used to simulate the experiment. The results show that the fuzzy PID control is obviously better than the traditional PID control, the overshoot of the system is significantly reduced, the speed of dynamic regulation is obviously accelerated; the realization of the grid of compound and coordinated intelligent control strategy for fuzzy control and fuzzy PID control enhances the realtime and reliability of the system control and greatly improves the performance of the system control.
