The technology of use of electric power of the wind power plants for direct replacement of fuel in the thermal cycles of the heat power plants is offered in the paper. The technology avoids solving the problems of ensuring the quality of electricity and the operational redundancy of the wind power in the power systems, as well as permits combining the achievements of traditional (gas turbine and steam and gas technologies, combined-cycle technologies and heating) and non-traditional renewable energy. The energy and environmental effects from the application of the proposed technology are shown, the technological advantages of the proposed schemes are considered, providing them with a wide scope of practical use both in local and in large power systems. The implementation and development of the proposed technology will allow extending and expanding business for manufacturers of steam turbine and gas turbine equipment, including the transition to the hydrogen power. The proposed technologies are protected by the patent.

“…A highly prevalent practice in tower plants for the receiver controller is to regulate the outlet temperature by adjusting the mass flow of the molten salt (Buck and Schwarzbözl, 2018). A solar field controller is used to determine all the aiming points and consequently the setpoints for the local controllers that act upon each heliostat.…”

Tuning Analysis and Optimization of a Cluster-Based Aiming Methodology for Solar Central Receivers

The challenges encountered while concentrating solar radiation from multiple heliostats into a relatively small receiver have inspired numerous aiming methodologies to distribute such concentrated radiation. Likewise, this concentrated radiation, denominated heat flux, needs to satisfy certain constraints that primarily depend on the receiver geometry, its building materials, the operating mass flow of the heat transfer fluid, and the overall solar radiation conditions. A recent study has demonstrated the effectiveness of an aiming strategy wherein a group of heliostats use a single parameter for the entire cluster and achieve the desired heat flux profile by adjusting the tuning parameters. Along similar lines, the current study was conducted to find the optimal values and the effect of two such parameters. The first parameter limits how far the aiming point of the heliostat can move from the equator line of the receiver, while the second represents its direction (upward or downward) from this line toward the edge of the receiver. Each section of a solar field was subdivided; both parameters were estimated for each subgroup, and their effect on the heat flux profile was determined. Furthermore, a parametric study was conducted using three sets of constraints for the optimization procedure. This procedure resulted in a heat flux profile that accomplished the constraints given by the allowable flux density for the receiver during the design day. The improvement using the optimal tuning parameters for the design scenario reached around 27%. Further analysis of the set of optimal values showed an adequate performance of the system at different times of the day and different days of the year. Finally, this study demonstrates how the calculated values function as a starting point for implementing the aiming methodology in different solar field and receiver combinations.

“…However, this is a hot debatable topic regarding both technologies. Ivanpah Solar Electric Generating System (ISEGS), which is the world's largest CSP plant with a capacity of 377MW, uses ST technology and has three stages 10 . At the same time, (SEGS) is the world's second‐largest CSP plant with a capacity of 340 MW and operating in eight segments using PT technology.…”

India has abundant solar power assets. Many districts get better than expected insulation compared with different parts of the world. The essential innovation for incorporating and changing sun‐based energy into electrical energy in India depends on photovoltaic (PV) cells. Concentrated solar power (CSP) plants have barely added to the nation's general introduced solar‐based force limit. The difficulties that have restrained the development of CSP and CST are part of the discussion and potential arrangements recommended. The primary difficulties for CSP and CST are identified as the absence of a dependable direct normal irradiance database, indigenous assembling, and rivalry from PV. The after‐effects of a contextual analysis evaluated the effect of indigenous assembling and economies of scale on capital expenses and levelized cost of power. We will evaluate the current status of CSP plants in this paper. The paper shows different incorporated technologies in solar thermal application in India with indigenous manufacturing and the energy policy supporting the solar thermal analyzing the barriers to implementation of Jawaharlal Nehru National Solar Mission. Also, the techno‐economic evaluation of the CSP and CST is covered. This paper provides a framework of CSP and CST technology in India's industrial sector with their impact on goods and services provided by the sector and the cost‐effectiveness of the product and technology. Furthermore, the environmental aspects and base electrical load accumulating are researched, and various policy measures and amendments are suggested to the government from this study‐based study.
