Wind–Hydro Microgrid and Its Control for Rural Energy System

Control scheme for wind–solar photovoltaic and battery‐based microgrid considering dynamic loads and distorted grid

“…Differentiating () with respect to time to derive the phase estimation of filter [20, 21], $$$\frac{d\theta }{dt}=\frac{{\hat{v}}_{\mathrm{\alpha g}}\frac{d{\hat{v}}_{\mathrm{\beta g}}}{dt}-{\hat{v}}_{\mathrm{\beta g}}\frac{d{\hat{v}}_{\mathrm{\alpha g}}}{dt}}{{\hat{v}}_{\mathrm{\alpha g}}^{2}+{\hat{v}}_{\mathrm{\beta g}}^{2}}=\frac{{\hat{v}}_{\mathrm{\alpha g}}\frac{d{\hat{v}}_{\mathrm{\beta g}}}{dt}-{\hat{v}}_{\mathrm{\beta g}}\frac{d{\hat{v}}_{\mathrm{\alpha g}}}{dt}}{{V}_{t}^{2}}$$$ …”

Ant lion algorithm for optimized controller gains for power quality enrichment of off-grid wind power harnessing units

“…In this study, they compared their algorithm with other algorithms for optimal dynamic performance of load frequency control for diesel-tidal hybrid power generation. Pathak et al [16] developed a renewable wind-hydro system to demonstrate a least-mean-square with reweighted control approach for solutions in power quality. Naidu et al [17][18] discussed a modified enhanced phase-locked loop and sliding mode observer control algorithm for a dynamic voltage restorer with optimization of proportionalintegral (PI) gains using particle swarm optimization (PSO) and Harris Hawks optimization algorithms for problems in power quality.…”

Day-Ahead MPC Energy Management System for an Island Wind/Storage Hybrid Power Plant

“…A way of dealing with these problems consists of setting-up hybrid power plants (HPPs), which combine wind turbines with production or storage technologies. In order to manage the energy to mitigate the wind generated power fluctuations, HPPs can consider renewable sources coupled with conventional/renewable power production, e.g., wind-diesel hybrid systems [6,7], wind-thermal [8,9], wind-hydro [10,11], and wind-solar systems [12,13]. It is also possible to combine wind production with storage systems, like batteries, fuel cells, and/or hydrogen storage.…”
