Summary This paper presents hybrid photovoltaic (PV)‐wind‐battery energy storage network tied to three‐phase utility grid side inverter using fuzzy logic proportional integral derivative‐improved second‐order generalized integrator‐quadrature signal generator‐phase locked loop (FLPID‐ISOGI‐PLL) for power quality enhancement at the consumer side terminals. An advanced ISOGI‐PLL control strategy is implemented to separate the fundamental constituent of each phase load current without sensing other phase currents, which makes phase independent and reliable. It has several characteristics, such as improved hybrid system (HS) power penetration, load sharing, and power factor correction. Additionally, FLPID adaptive voltage controller is incorporated in the presented scheme to enhance dynamic operation of the system and also keeping the power balance between the dc and ac sides by maintaining the dc bus voltage. Moreover, the photovoltaic system's feed‐forward constituent is incorporated in the proposed technique, which improves the system dynamic performance and minimizes oscillations in grid currents. The outcomes of the advanced control strategy are found adequate for enhancing active power filter (APF) performance at the consumer side terminals under several operating conditions. The proposed control technique is computationally analyzed by simulating the system through MATLAB/SIMULINK under steady state, dynamic, load removed, and unbalanced grid voltage conditions. The competency of an advanced control approach is examined with hardware‐in‐loop (HIL) co‐simulation using FPGA Virtex‐7 VC‐707 via very high speed integrated circuit hardware description language (VHDL) code generation. Finally, the simulation outcomes are verified through a real‐time prototype laboratory platform using FPGA Virtex‐7 VC‐707 evaluation kit, and the total harmonic distortion (THD) analysis of injected grid currents is tabulated under different operating scenarios and found good within the IEEE‐519 standard limits.

The large scale penetration of renewable energy resources has boosted the need of using improved control technique and modular power electronic converter structures for efficient and reliable operation of grid-connected systems.This study investigates the performance of a grid-connected 3-phase 3-level neutral-point clamped voltage source inverter for renewable energy integration by using improved current control technique. For medium or high-voltage grid interfacing, the multilevel inverter structure is generally used to reduce the voltage stress across the switching device as well as the harmonic distortion.The neutral-point clamped voltage source inverter is controlled by using decoupling technique along with the proper grid synchronization via moving average filter-based phase-locked loop. The moving average filter-based phase-locked loop is used to reduce the delay in grid angle estimation under balanced as well as distorted grid conditions. A Lyapunov-based approach for analysing the stability of the system has also been discussed. In this study, the hardware-in-loop (HIL) simulation of the control algorithm and the grid synchronization technique is realized using Virtex-6 FPGA ML605 evaluation kit. The performance of the system is analyzed by conducting a time-domain simulation in the Matlab/Simulink platform and its performance is examined in the HIL environment.The simulation and the hardware cosimulation results are presented to validate the effectiveness of the proposed control scheme.

With the large amount of distributed generation in use, the structure of the distribution system is increasingly complex. Therefore, it is necessary to establish a method to improve load reliability. Based on the reliability model of distributed generation, this paper investigates the time sequential simulation of a wind/solar/storage combined power supply system under off-grid operation. After classifying the load by power supply region, the load weight coefficient is established, which modifies the reliability index of the load point and system. The modified expected energy not supplied (EENS) is adopted as the objective function, and the particle swarm optimization algorithm is used to solving the optimal energy scheduling for improving the load reliability. Finally, the load reliability is calculated with a hybrid method. Using the IEEE-RBTS Bus 6 system as an example, the correctness and validity of the proposed method are verified as an effective way to improve load reliability.
