Design of wind-solar-diesel-storage system

Is a standalone solar–wind-pumped storage system effective for an isolated microgrid?

This paper presents a techno-economic analysis of the standalone hybrid solar–wind-pumped storage system for an isolated microgrid. The effectiveness of the proposed system and optimization method was examined through comparison with undersized and oversized system.

Can a hybrid solar-wind-pumped storage system be designed in standalone mode?

The purpose of this study is to optimize the system design of a proposed hybrid solar–wind-pumped storage system in standalone mode for an isolated microgrid of a scale of a few hundred kW. The initial design process of the system’s major components is presented, and then optimized based on a techno-economic evaluation.

What is a solar power system?

It consists of photovoltaic (PV) array and wind turbine (WT), pumped hydro storage, end-user and control station. The whole system is isolated from the utility grid, hence called standalone/autonomous system, aiming for remote areas where utility extension is very expensive or impossible.

Do wind turbines reduce the cost of energy storage under LpSP?

In addition, the system performance of hybrid solar–wind, solar-alone and wind-alone systems with pumped storage under LPSP from 0% to 5% is investigated and compared. Results demonstrate that addition of wind turbine can result in a lower cost of energy (COE) and help reduce the size of energy storage.

What is the difference between a diesel generator and a wind turbine?

Wind turbines contribute approximately 1%, while the diesel generator covers only 3% of the load, in scenario one. For scenario two, we find that the photovoltaic system covers 45% of the load, while 53% of the required energy is covered by batteries. Wind turbines contribute approximately 1%, while the diesel generator covers only 2% of the load.

What is the difference between PV/diesel/batteries & wind/diesel / batteries?

The main difference between the PV/Diesel/Batteries and Wind/Diesel/Batteries systems lies on the renewable resource characteristics and the correlation between solar and demand profiles. Because of this, the operational costs with diesel in the Wind/Diesel/Batteries system are higher.
