quency regulation services. However, modern power systems with high penetration levels of generation. Therefore, de-loading of renewable energy generations to provide frequency reg- ulation is not technically and economically viable. As such, energy storage systems, which support are the most suitable candidate to address these problems.
It is worth mentioning that BESS is presently dominant for frequency and diversity of materials used [1, 10, 11]. Among diferent battery chemistries, lithium-ion that outnumber their limitations [1, 11]. seconds [12, 13]. Hence, PFR services require continuous power for a relatively long period of time .

In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
Since the battery energy storage does not participate in the system frequency regulation directly, the task of frequency regulation of conventional thermal power units is aggravated, which weakens the ability of system frequency regulation.
The battery energy storage system (BESS) is a better option for enhancing the system frequency stability. This research suggests an improved frequency regulation scheme of the BESS to suppress the maximum frequency deviation and improve the maximum rate of change of the system frequency and the system frequency of the steady state.
The results of the study show that the proposed battery frequency regulation control strategies can quickly respond to system frequency changes at the beginning of grid system frequency fluctuations, which improves the stability of the new power system frequency including battery energy storage.
The au thors reported that floating PV systems are less expensive than wind-based floating power u nits. Integrating floating power units enhances p ower generation and reduces operation and mainten ance costs accordingly. The wind energy density is promising away from offsho re, which helps improve the performance of hybrid systems.
The optimized share in power generation is 74% wind power and 26% solar photovoltaic, which results in 8% additional energy generation from renewable s ources. Therefore, it is concluded that floating wind power units have the capability to meet the surplus po wer demands and conv ey additional benefits to integrated power systems. Access
According to them, the combination of floating PVs with wind yards is technically and economically beneficial. Adding solar power to transport electrical energy from wind farms increases the usage of offshore electrical cables. The revenue obtained from integrated PV cum wind power the floating PV system.

4 Kazakhstan’s vast and cost-efficient wind energy potential offers a particularly strong foundation for scaling up renewable energy capacity. The country could increase its wind power capacity to 10 gigawatts by 2035, twice as much as the government is currently planning – or even more.
Jain, Das made a Geographic Information System (GIS) -based multi-criteria assessment of the solar PV and onshore wind energy potential in India. However, since analysis confined to the spatial scale only was not comprehensive, further analysis on the complementary potential of wind power and PV power at temporal scale was needed.
China has made considerable efforts with respect to hydro- wind-solar complementary development. It has abundant resources of hydropower, wind power, and solar power and shows promising potential for future development.
