“…They include the following power production technologies: onshore wind turbines with medium specific capacity and medium hub height, utility-scale PV without tracking and parabolic trough with 6 to 8 hours storage (equivalent to SM1.5). In our study, we neglect the cost of TES capacity as TES is cheap [14]. The system cost is much more sensitive to the cost of the power technologies than to the cost of storage [29].…”

“…Optimal mixes for penetrations lower than the maximum tend to include a positive share of PV, whatever the combination. As shown in Appendix D.2, when the maximum-cost constraint is active and if k 0 = k * is the index of the capacity which is installed to maximize the mean penetration, the first capacity k that is installed after k 0 for lower penetrations is the one that minimizes the quantity (14),…”

“…Table 7. Ratios (no units) given by (14) to identify the second capacity to be installed as the mean penetration is decreased from its maximum. Last, we can see that the actual mix (gray cross in the left panels of Figures 4 and 5) is to the right of the constrained global front (blue line), whatever the combination.…”

“…CSP, on the other hand, has high cost of capital [10], even its Levelized Cost of Electricity (LCOE) tends to be lowered by its high capacity factor [11], and therefore requires policy mechanisms to lower the investment risk [12,13]. In addition, although not commonly used in existing PV farms, batteries are likely to make PV more expensive than CSP combined with relatively cheap TES [14].…”

In this paper, we analyze the sensitivity of the optimal mixes to cost and variability associated with solar technologies and examine the role of Thermal Energy Storage (TES) combined to Concentrated Solar Power (CSP) together with time-space complementarity in reducing the adequacy risk—imposed by variable Renewable Energies (RE)—on the Moroccan electricity system. To do that, we model the optimal recommissioning of RE mixes including Photovoltaic (PV), wind energy and CSP without or with increasing levels of TES. Our objective is to maximize the RE production at a given cost, but also to limit the variance of the RE production stemming from meteorological fluctuations. This mean-variance analysis is a bi-objective optimization problem that is implemented in the Emathsizesmall4CLIMmathsizesmall modeling platform—which allows us to use climate data to simulate hourly Capacity Factors (CFs) and demand profiles adjusted to observations. We adapt this software to Morocco and its four electrical zones for the year 2018, add new CSP and TES simulation modules, perform some load reduction diagnostics, and account for the different rental costs of the three RE technologies by adding a maximum-cost constraint. We find that the risk decreases with the addition of TES to CSP, the more so as storage is increased keeping the mean capacity factor fixed. On the other hand, due to the higher cost of CSP compared to PV and wind, the maximum-cost constraint prevents the increase of the RE penetration without reducing the share of CSP compared to PV and wind and letting the risk increase in return. Thus, if small level of risk and higher penetrations are targeted, investment must be increased to install more CSP with TES. We also show that regional diversification is key to reduce the risk and that technological diversification is relevant when installing both PV and CSP without storage, but less so as the surplus of energy available for TES is increased and the CSP profiles flatten. Finally, we find that, thanks to TES, CSP is more suited than PV and wind to meet peak loads. This can be measured by the capacity credit, but not by the variance-based risk, suggesting that the latter is only a crude representation of the adequacy risk.

“…It becomes a unique source of solar energy in its output that can be shifted over time and controlled in response to system requirements, allowing for the provision of a wide range of grid services. Unlike regular perception, CSP has no competition with Solar PV due to difference to their role, CSP with Thermal Energy Storage rather supports its commercialization by being a remedy to its intermittency (Hamilton, Husted, Newman, Braun, & Wagner, 2019). If dispatchability and thus storage is considered then Concentrated solar thermal is both technically and financially preferable over commercialized renewables (Rahouma et al, 2017).…”

Pakistan is identified to be one of the next-11 the top emerging economies of the world after the BRICS. This emphasizes the establishment of a competitive electricity market that can fulfil the demand of the country considering the environmental concerns. In this scenario reliability of power is something that cannot be compromised. Dispatchable power stations play a major role in balancing supply and demand; this balance is essential for maintaining the power cuts free country. All dispatchable power stations incorporate some form of storage particularly thermal or chemical (i.e. a stored fuel). Earlier dispatchable power was regarded as the generation which can start quickly and meet the peak demand requirements but arrival of renewables in power system has increased worth of its presence since it has just not to supply peak demand but also to meet during the unavailability of other renewable energy sources because of their intermittent behavior meanly at times of dark hours and slow wind speed. This study considers the viability of Concentrated Solar Thermal Power in Pakistan and thoroughly analyses several characteristics i.e., Availability of fuel, water, road and communication network, flexibility and environmental impacts of the technology for the cite of Tharparkar.
