Optimized PID Based Load Frequency Control of a Hybrid Microgrid

S. M. Aminu*, Y. Jibril, A. Abdulkarim, A.S. Abubakar

This research presents the development of an optimized PID based load frequency control of a hybrid microgrid. The micro-grid (MG) concept allows the renewable energy sources to operate in both synchronized grid and islanded/stand-alone mode. These modes of operations of the MG have made it smart, hence require intelligent coordinated control strategies. The existing control strategies of the MG s...

Integrated Economic and Emission Dispatch of Hybrid Thermal-Photovoltaic Generation

I. Abdullahi*, U. Musa, B. Musa, A. Aliyu, Abdullahi Bala Kunya, S.A. Alkali, S. Awaisu

Due to the increasing demand for qualitative electric energy at a competitive price and reduced environmental deterioration, electric power generation systems should be optimally dispatched. In this paper, the Integrated Economic and Emission Dispatch (IEED) of hybrid thermal-photovoltaic power plants using Bat (Chiroptera) Inspired Algorithm (BIA) is presented. The IEED technique entails determin...

Development of Load Frequency Control of Two Area Interconnected Network Incorporated with Distributed Energy Sources

Adamu, Ahmed Kana*, A. B. Kunya, A.S. Abubakar

The frequency of power systems is highly sensitive to load changes, and the increasing integration of distributed energy sources (DESs) further complicates frequency stabilization. To address these challenges, Load Frequency Control (LFC) is implemented to maintain frequency within acceptable limits. This work proposes a grasshopper optimization algorithm based on proportional integral derivative ...

A Study on State Estimation of Synchronous Generator using an Improved Unscented Kalman Filter Algorithm

Yahaya Ismail*, B. Jimoh, Adamu Abubakar Sa’idu

An enhanced Unscented Kalman Filter (UKF) technique for synchronous generator state estimation is presented in this study. The suggested approach overcomes the drawbacks of conventional UKF in managing noise and nonlinearities in power systems. Comparative analysis and validation are made on the tracking performance of Normal Ukf and Improved Ukf (SR-Ukf) algorithms and the simulation results show...

Development of Optimal Electricity Management Systems to Minimize Resources and Losses using Particle Swarm Optimization Techniques: A Case Study for UDUS

A. U,Lawan*

Hybrid energy systems (HESs), have played an important role as clean and efficient source of electricity generation. HESs are often formulated as an optimization problem which is solved mostly using metaheuristics techniques. The conventional objective function is based on levelized cost of energy (LCOE), the lowest loss of power supply probability (LPSP), and the maximum renewable factor (REF) as...
