Due to the depletion of fossil fuels and environmental concerns, renewable energy has become increasingly popular. Even so, the economic competitiveness and cost of energy in renewable systems remain a challenge. Optimization of renewable energy systems from an economic standpoint is important not only from the point of view of researchers but also

Completed in 2007, Mainly coal-fired, solar energy only used to preheat boiler feed water.
The present study investigates the viability of employing Solar parabolic trough collectors (PTC) and parabolic dish collectors (PDC) integrated with thermal energy storage (TES) as the primary heat source for a steam-powered Rankine cycle, aimed to produce 5500 kW power for green hydrogen generation.
The purpose of this study is to optimise the dimensions of the collector in a solar chimney power plant with entropy generation minimisation (EGM) method.

Sahu et al. [19] presented a large-scale method for generating electricity for a house. A trumpet-shaped primary reflector is utilized in their design to bridge the gap between the TEG and the dish collector. This system has an average effective electrical efficiency of 0.2 %–0.7 %, and the water used to remove heat from the TEG can be reused as hot water.
There are two methods for solar power generation, one is photothermal-electric conversion, and the other is direct photoelectric conversion. 1. Photothermal power conversion Generally, the solar heat collector converts the absorbed heat into the vapor of the working fluid, and then drives the steam turbine to generate electricity.
Concentrating solar Fresnel technology is a promising option for renewable solar heat generation in industrial processes. There are many sectors with medium and low-temperature heat demand in which water could be used as a heat transfer fluid (HTF), without the drawbacks of thermal oils in indirect steam generation systems.
The solar cycle is connected to the power generation cycle by a steam generator. The cogeneration system proposed in this research transfers the energy collected from the sun by the solar collector to a steam generator to be converted into electricity in the organic Rankine power generation cycle.
Solar installations require minimal water compared to traditional power generation methods that are consuming this valuable resource. Economically solar energy

The utilisation of medium temperature (200–300 °C) concentrating solar collectors (e.g., parabolic trough collectors) to displace the extraction steam to high temperature/pressure feedwater heaters (FWHs) of an RRC power plant is the most common target for an SAPG plant.However, the system can be configured with the solar thermal energy
The solar collector field in SACPGS is to provide heat for feedwater, and then the heated feedwater is injected into the boiler to produce high-pressure and high-temperature steam. Subsequently, the steam can work in turbines to output electricity. Due to the indirect power generation mode, solar contribution in SACPGS is not evident.

The working fluid within solar collectors typically comprises air, water, or oils [19]. Solar collectors are categorized into two main types: stationary (or non-concentrating), and concentrating. In stationary solar collectors, the intercept area and the absorbing area for solar radiation are equivalent.
The preheating of the feedwater in a Regenerative Rankine Cycle power plant with solar thermal energy, termed Solar Aided Power Generation, is an efficient method to use low to medium temperature
A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar

The electric power generation from solar thermal energy by coupling different power cycles is the latest application. Solar collectors are the devices, used to convert solar irradiance into thermal energy. They are broadly categorized into two types, i.e., concentrating and non-concentrating collectors [7]. Evacuated tube solar collectors (ETSC
Solar collectors are crucial components of a Solar Thermal Power plant (STP) which are required to be within a certain feasible range in order to operate and provide solar thermal resources and intermittent inputs. The closed-loop controller design for solar collectors enhances the lifespan of STP.
The utilisation of medium temperature (200–300 °C) concentrating solar collectors (e.g., parabolic trough collectors) to displace the extraction steam to high temperature/pressure feedwater heaters (FWHs) of an RRC power plant is the most common target for an SAPG plant.
The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non- water heating devices such as solar cookers or solar air heaters. Solar thermal collectors are either non-concentrating or concentrating.
Generally, the solar collectors behave as a heat exchanger for converting the solar energy to the internal thermal energy of solar heat transfer fluids that are flowing in the solar collectors. The solar collectors can be divided as concentrator collectors and non-concentrator collectors .
However, Zhou et al. found that using non-concentrating solar collectors (i.e., evacuated tube (ET) collectors) still has higher net land based solar thermal to power efficiencies over using concentrating solar collectors (i.e., parabolic trough (PT) collectors) .
One of the key parameters for the enhancement of the solar energy conversion is to increase the solar collector’s performance by optimizing the geometry of the collector, changing the working fluid and selecting proper materials for the absorber tube. Among all solar collectors, parabolic trough collector (PTC) is the well-performed one.
