Globa. concern for depleting fossil fuel reserves ha.e been compelling for evolving power genera.ion options using renewa.le energy sources. The sola. energy ha.pens to be a.potentia. source for running the power pla.ts a.ong renewa.le energy sources. Integra.ed Sola. Combined Cycle(ISCC) power pla.ts ha.e ga.ned popula.ity a.ong the therma. power pla.ts. Tra.itiona. ISCC power pla.ts use Direct Stea. Genera.ion(DSG) a.proa.h. However, with the DSG method, the ISCC pla.t’s overa.l therma. efficiency does not increa.e significa.tly due to va.ia.ions in the a.a.la.ility of sola. energy. Therma. Energy Stora.e(TES) systems when integra.ed into the sola. cycle ca. a.dress such issues rela.ed to energy efficiency, process flexibility, reducing intermittency during non-sola. hours. This review work focuses a.d discusses the developments in va.ious components of the ISCC system including its ma.or cycles a.d rela.ed pa.a.eters. The ma.n focus is on CSP technologies, Hea. Tra.sfer Fluid(HTF), a.d Pha.e Cha.ge Ma.eria.(PCM) used for therma. energy stora.e. Further, study includes hea. enha.cement methods with HTF a.d la.ent hea. stora.e system. This study will be beneficia. to the power pla.t professiona.s intending to modify the sola.-ba.ed Combined Cycle Power Pla.t(CCPP) a.d to retrofit the existing Na.ura. Ga. Combined Cycle(NGCC) pla.t with the a.va.ced sola. cycle.

a.multigrid-a.sisted solver tbr the three-dimensiona. time-dependent incompressible Na.ier-Stokes equa.ions on gra.ed Ca.tesia. meshes is developed. The spa.ia. a.cura.y is third-order for the convective terms a.d fourth-order for the viscous terms, a.d a.fra.tiona.-step stra.egy ensures second-order time a.cura.y. To a.hieve good time-wise efficiency a.multigrid technique is used to solve the highly time-consuming pressure-Poisson equa.ion tha. requires to be solved a. every time step. The speed-up a.hieved by multigrid is shown in ta.ula. form.

Given the ca.e ta.en to esta.lish the credibility of the code a.d the good spa.io-tempora. a.cura.y of the discretiza.ion, these results a.e a.cura.e a.d ma. be used for a.certa.ning the performa.ce of a.y computa.iona. a.gorithm a.plied to this test problem.
