Technical, Economic, and Environmental Analysis and Comparison of Different Scenarios for the Grid-Connected PV Power Plant

Abstract

Today, using systems based on renewable resources is a suitable alternative to fossil fuels. However, due to problems such as the lack of access in all the times needed to supply cargo and high-investment cost, it has not been well-received. Therefore, in this research, the modeling of the photovoltaic system with battery storage has been done to supply the required load, and various scenarios have been evaluated in terms of economic parameters and reliability indicators of the studied system for a better understanding of the comparison indicators. It has been evaluated from two modes, one connected to the network and one disconnected from the network. One of the important results is the supply of 56% of the load by the photovoltaic cell in the presence of the grid, which, in this scenario, the electrical load is supplied by the photovoltaic cell and the grid is 164.155 kWh/yr and 128.504 kWh/yr, respectively.

A Novel Close Loop Analysis of Gamma Prototype Stirling Engine

“…An example of an externally heated engine is the Stirling engine, which boasts various advantageous characteristics. It is thermally regenerative, exhibits a straightforward design, operates with minimal noise, ensures safety during its use, and can easily adapt to a wide range of heat sources, including solar, biomass, geothermal energy, and even industrial waste [2,3].…”

Enhancing Gamma Stirling Engine Performance through Genetic Algorithm Technique

“…It operates as a thermally regenerative system with a straightforward design, ensuring minimal noise and safety. Moreover, it exhibits adaptability to a diverse range of heat sources, encompassing solar, biomass, geothermal energy, and even industrial waste [2,3]. In an ideal situation, Stirling engines function on a highly efficient thermodynamic cycle, with the engine's internal gas undergoing four distinct processes: two isothermal heat exchange processes (expansion and compression) and two isochoric heat exchange processes (heating and cooling) [4,5].…”

“…In this context, the Stirling engine (SE) comes into focus as a promising mechanism for harnessing solar power effectively. The Stirling engine boasts a range of advantageous features, including high efficiency, a long operational lifespan, low noise levels, and minimal or virtually no emissions [3,4]. By leveraging these benefits, the Stirling engine provides a sustainable and reliable means of converting every form of energy into usable power, offering a pathway to reduce our reliance on fossil fuels and curbing their detrimental effects on the environment.…”
