In This research PIDF (Proportional Integral Derivative with Filter) is suggested to control the ACE (area control error) signal of automatic generation control circuit (AGC) for two-area multi units system under deregulated conditions, each area consist of two thermal reheat units with physical GRC (generating rate constrain). The parameters of the PIDF controller are tuned using PSO (particle swarm optimization) technique. To improve the system performance, Redox Flow Batteries (RFB) is presented in one area and one of FACTS components IPFC (Inter Line Power Flow Controller) is installed in tie line. The performance of the proposed controller is assessed under different working conditions of deregulated power market. Finally, a comparison will be made on the system response when testing with varying the load conditions and system parameter through MATLAB environment 2015Rb.

In distribution network, there are multiple constraint condition on the capacity allocation of distributed generation, this text takes the maximization of power generation benefit as the premise, and adopts genetic algorithm to implement the optimal allocation of distributed generation’s capacity. The algorithm uses the minimum distribution network power consumption as objective function, the admissible deviation of supply voltage and capacity accessed to common point not more than 10MVA are taken as the constraint condition, and the Newton-Raphson method is adopted to carry out power flow calculation. Based on the algorithm, the specific planning program flow diagram is given, and combining Jiangxi Gongqing city distribution case, capacity planning design is carried out to conclude the optimal node access capacity. The conclusion of the study can play a better guiding role for the planning and design of distribution network including distributed generation.

This research article aims to develop Load Frequency Control (LFC) of equal three area with individual area comprises single thermal sys-tem and wind system and appropriated 3% of Generation rate constraint (GRC) is considered for thermal system to make non-linearity to overall system. For automatic generation control (AGC) the proposed secondary controller is a two degree of freedom (DOF) based frac-tional order Proportional, Integral, Derivative (PID) controller and used to reduce error for this study. For optimizing the gains of this pro-posed controller in a suitable manner a newly deterministic algorithm called Whale Optimization algorithm (WOA) is applied. Comparative performance analysis of different controllers like FO-2DOF-PID, 2DOF-PID, and PID is done in respect of settling time and peak over-shoot. Apart from this to improve quality of different dynamic responses some FACTS devices like Interlined power flow controller(IPFC), Static synchronous series compensator (SSSC) and Thyristor controlled series capacitor (TCSC) are implemented with FO-2DOF-PID controller and for superiority analysis a comparison is made between above optimized controllers.
