Optimal operation of basin‐based tidal units equipped with hydro‐pumps

Abstract

Due to their clean nature, high capacity and accurate predictability, the basin-based tidal units can be integrated into bulk power systems. The major problem of these units is the high investment cost of barrage construction, and so, among different renewable resources, these units are less developed. For making the tidal barrages cost-effective, new methods should be implemented to increase their produced power that results in the reduction of electricity price. For this purpose, this study suggests new techniques for optimally operating tidal units equipped with hydro pumps. Here, to increase the produced power and energy of the tidal units, at each time, the number of turbines, sluices and hydro-pumps is optimally determined to yield the maximum produced energy of the generation unit using the particle swarm optimization method. For satisfying the effectiveness of the suggested approach, the optimal operation of a tidal unit installed on the estuary of Bacanga is done and the impact of optimal dispatching of the turbines, sluices and hydro-pumps on produced energy of the unit is studied. It is deduced from numerical results that the generated energy of the plant during 24 h is increased by 17% with the implementation of the proposed operation plan.

Optimal scheduling of the stand‐alone micro grids considering the reliability cost

“…As can be seen in Figure 15, the PSO algorithm has converged with good velocity. The optimal operating cost of the understudied micro grid, the operating cost of fuel-based generation FIGURE 14 The hourly failure rate of the wind turbine, tidal turbine and PV system components. units calculated in the optimal scheduling of the micro grid and the penalty associated with interrupted loads calculated in the optimal scheduling of the micro grid would be 18738$, 15492$ and 3246$, respectively.…”

“…In the current study, a micro grid containing stream kind tidal unit, wind turbine and photovoltaic systems is studied. In [14], optimal planning of a micro grid containing tidal barrage equipped to the hydro‐pumps, photovoltaic systems and battery storage devices is examined. In the current study, optimal properties of barrage kind tidal unit including number of turbines, sluices and hydro‐pumps, turbine tip and hub diameters and sluice width are obtained for generating maximum energy of tidal unit.…”

“…Then, number of photovoltaic panels and batteries are determined to provide the required demand in minimum cost. Paper [15], performs optimal operation of the micro grids containing barrage kind tidal unit equipped with hydro‐pumps. In the current study, to optimize the operating cost of the micro grid, particle swarm optimization technique is applied.…”

A Novel Design and Analysis Adaptive Hybrid ANFIS MPPT Controller for PEMFC-Fed EV Systems

“…Due to these drawbacks, most of the electric vehicle industries focus on renewable energy systems which are tidal, wind, solar, and hydropower systems [1]. In article [2], the authors discussed the tidal power supply system. Here, at the high tide period, the water fows from the sea into a water turbine to generate electricity for the local consumers.…”
