Abstract

This study presents load-frequency-control of a two-area hybrid power system (HPS) incorporating distributed generation, geo-thermal plant, thermal plant and electric-vehicle. Such a complex system with non-linearities leads the power system towards more complexity and accordingly requires a resilient controller to handle such complexity. In this regard, optimal cascaded proportional integral – multistage proportional integral derivative (cascaded PI-MSPID) is explored for developed power system. The efficiency of optimal controller is validated by comparing it with other controllers. The influence of flywheel energy storage on system dynamics is demonstrated. Further, the electric vehicle’s participation in enhancing the system stability is presented. Moreover, the developed system is subjected to an intense load deviation which is a practical data taken from one of the literature. It is demonstrated that responses achieved for proposed cascaded PI-MSPID controller effectively handles the system disturbances, which reflects the strength of proposed cascaded PI-MSPID controller.

分布式发电与电动汽车混合动力系统的最优控制

研究了一种由分布式发电、地热电厂、热电厂和电动汽车组成的两区混合电力系统的负荷-频率控制。这种具有非线性的复杂系统导致电力系统变得更加复杂，因此需要弹性控制器来处理这种复杂性。为此，针对发达电力系统，探索了最优级联比例积分-多级比例积分导数(级联PI-MSPID)方法。通过与其他控制器的比较，验证了最优控制器的有效性。论证了飞轮储能对系统动力学的影响。进一步提出了电动汽车对提高系统稳定性的作用。此外，开发的系统受到强烈的负载偏差，这是一个实际的数据，取自一个文献。结果表明，所提出的级联PI-MSPID控制器所获得的响应能有效地处理系统扰动，这反映了所提出的级联PI-MSPID控制器的强度。
