Some suggestions for solar industry development in Kazakhstan are put forward in this paper, based on the analysis of global solar energy industry development model.
Kazakhstan is developing solar energy technologies, namely production of photovoltaic modules using local silicon. As Kazakhstan is rich in silicon (85 million tons), production of silicon solar batteries on the domestic market was started (Sim, 2015).
During the summer months (June – August), due to its geographical location, the southern part of Kazakhstan receives direct solar radiation for the most of the daylight hours which constitute 83 – 96% of the maximum possible value.
Kazakhstan is rich in different mineral resources, oil, gas and coal being the most important ones for the economy of the country. Therefore, since independence, the government of Kazakhstan mainly focused on developing the fossil fuel industry rather than alternative energy resources.
Diesel is the single largest component (product) in Kazakhstan's refinery slate and in its domestic consumption balance; widely consumed within Kazakhstan, diesel is used across many economic sectors, while transportation (trucking) is the single largest consumer. Kazakhstan remained a (small) net importer of diesel each year during 2016-22.
While the northern part of the country receives approximately 2,000 hours of sunshine, the southern cities such as Kyzylorda and Shymkent receive 2,936 and 2,892 hours of sunshine annually, which is enough to meet the electricity demand of southern Kazakhstan.
Annual potential of solar energy is estimated to reach 2.5 billion kWh. Table 1 shows data on monthly and annual values of the solar radiation for three areas: Fort-Shevchenko (on the coast of the Caspian Sea), the Aral Sea basin (near the Aral Sea coast) and Almaty (southeast Kazakhstan).
The energy storage charging pile achieved energy storage benefits through charging during off-peak periods and discharging during peak periods, with benefits ranging from 501. At an average demand of 50 % battery capacity, with 50–200 electric vehicles, the cost optimization decreased by 18.
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.
The results indicate that EV and charging piles diffusion do interact, and public attention plays a nexus role in EV and charging piles deployment. Reducing the electricity rate is the most effective policy approach to promote EV charging piles.
The endogenous relationships among EVs, EV charging piles, and public attention are investigated via a panel vector autoregression model in this study to discover the current development rules and policy implications from the historical panel data in China.
Furthermore, high-power direct-current (DC) charging piles, which are unsuitable for home installation, can provide much faster EV charging, making them ideal for urban areas, such as Madrid and Manhattan, where parking costs are high (Faria et al., 2014).

Adaptive tracking of electricity quantity, taking into account the State of Charge (SOC) of EESSs, is proposed to improve the efficiency of Energy Energy Storage Systems (EESS) and slow down the processes of battery degradation.

[PDF Version]The energy platform is made of three key components: the energy cloud for the generation, distribution and storage of electricity, the digital platform for industry and customers to jointly manage the energy infrastructure, and the transaction platform for trading and services.
Based on the analysis of the users' energy storage application modes and the upper bound of service fee payment, an energy storage planning strategy to maximize the platform operator's revenue is proposed.
In order to implement the energy platform, there is significant work to develop enabling technologies such as energy storage, power electronics, and mathematical and computing tools. Control and optimization of a large number of devices and players to ensure system-level performance also requires a large and sustained effort.
The energy platform is certainly an ideal mechanism for information sharing and exchange, but the security requirements put pressure on the development and implementation of new theories and technologies such as the block chain technology .
Innovative solutions play an essential role in supporting the transition to a new energy-saving system by expanding energy storage systems. The growth and development of energy storage systems should be central to planning infrastructure, public transport, new homes, and job creation.
Using PEST analysis, we demonstrated that governments, national officials, and people have key roles in expanding energy storage systems for renewable power integration.

In this paper, a simplified consensus-based distributed secondary control for BESSs in DC microgrids is proposed with only one virtually defined state variable being transmitted, where a cascaded control framework consisting of an SoC controller and a voltage controller is used to regulate DC bus voltages.
Chen et al. proposed a distributed cooperative secondary control for batteries in DC microgrids, a state variable related to the battery SoC is defined and it varies when BESSs switch between charging and discharging modes to achieve SoC balance, .
Also, battery and Super Capacitor (SC) banks are considered as secondary energy systems. The high power density and the fast dynamics of SCs combined with the high energy density and medium dynamics of batteries would be an ideal combination for FC vehicles.
While the vehicle moves and required power is lower than the sum of the nominal FC and PV power, the two secondary storage systems can be loaded using additional FC energy. In braking mode, charging the battery or SC depends on the degree of deceleration.
Hu et al. proposed a secondary control strategy with four controllers, including a current-sharing controller, an SoC balance controller, a virtual impedance correction controller, and a local reference voltage controller, they collectively achieve voltage regulation and SoC balance .
Without support of the main grid, the battery energy storage system (BESS) is an indispensable unit of islanded microgrids. Meanwhile, cyber attack is an inevitable issue with the application of advanced communication and control technologies in microgrids. 1.1. Battery energy storage system
For effective control of battery energy storage units, a Voltage–Power (V-P) reference-based droop control and leader–follower consensus method is employed. The control approach consists of primary and secondary control layers. The primary layer uses a V-P reference-based droop control strategy to allocate load components to storage units.
As demand for energy storage soars, traditional battery technologies face growing scrutiny for their cost, environmental impact, and limitations in energy density.
