With growth of renewable energy sources' use the uncertainty in power grids is increasing tremendously. Optimal control and the equipment dispatching become challenging task for both central supplier and power consumer. Implementation of smart approach gives opportunity to provide such control with less human resources and power losses. In the article recently used techniques for control and dispatching in central grid of Almaty is described. Beside that new smart control methods and their possibilities within power system of Kazakhstan are reviewed. As a result, best solutions for the power system's control in both small entities and central grid are proposed.

“…would have an overall increasing benefit on the deployed operations. Meanwhile, stand-alone hybrid energy systems have been proposed as valuable means of supplying energy to remote areas, such as isolated rural villages [4][5][6][7], and for various other purposes, such as medical clinic practices [8] or military operations [9][10][11].…”

A Smart Hybrid Energy System Grid for Energy Efficiency in Remote Areas for the Army

The current energy inefficiencies in relocatable temporary camps of the Armed Force troops create logistic challenges associated with fuel supply. The energy needs of these camps are primarily satisfied by diesel engine generators, which imply that a significant amount of fuel needs to be continuously provided to these camps, often built in remote areas. This paper presents an alternative solution, named Smart Hybrid Energy System (SHES), aiming towards significantly reducing the amount of fuel needed and minimizing transportation logistics while meeting camp energy demands. The SHES combines the existing diesel generators with solar power generation, energy storage, and waste heat recovery technologies, all connected to a microgrid, ensuring uninterrupted electricity and hot water supplies. All components are controlled by an energy management system that prioritizes output and switches between different power generators, ensuring operation at optimum efficiencies. The SHES components have been selected to be easily transportable in standard shipping 20 ft containers. The modularity of the solution, scalable from the base camp for 150 people, is designed according to available on-site renewable sources, allowing for energy optimization of different camp sizes in different climates.

“…On the other hand, one of the most important problems of the hybrid system is to optimally size the components of the HS. This dimension is realized, in order to generate enough energy to meet the demand of the locality with minimal investment and exploitation costs (Puglia et al, 2017;Halabi et al, 2017). Secondly, it should be noted that the optimal design of HS is complicated by intermittent renewable resources, uncertain demand, non-linear component performance, and a large number of variables (Sajed Sadati et al, 2018;Kaabeche and Ibtiouen, 2014).…”

The reported work was motivated by the energy needs in the Mauritania region and the utility of the search features of a software system, named HOMER (Hybrid Optimization of Multiple Energy Resources), for feasibility analysis of a hybrid power generation system (HS) for the Mauritanian northern coast. This study analyzed a sample of the available wind resources to meet the energy needs of these localities, using the HOMER software with the aim to search for the best possible configuration. A configuration was sought through this work which is considered with less intermittence in the system. In addition, given the relationship noted in the study between the influence of the average wind speed and the price of diesel in liters, it was also suggested to highlight configurations that exclude storage or that may decrease the size of the fuel. This, as a supplementary feature, also allowed, for example, to justify the additional cost generated by the insertion of the diesel group. In this context, five (5) values are given for the study of the price sensitivity of the liter of diesel; these values are proposed as follows: 1.05 $/L (current), 1.08, 1.1, 1.2 and 1.5 $/L (Maximum price). In another way, to carry out the sensitivity analysis through simulations that take into account the average wind speed, the values retained (4, 5, 6, 7 and 8 m/s (maximum speed)) to deepen the study of the behavior of configurations by HOMER software. Finally, we must remember the number of kilowatthours produced that may seem insignificant to the country's energy production capacity, but these few tens or hundreds of kilowatt-hours can revive all the hope of the localities of the Mauritanian northern coast. In short, we report here some interesting findings as a result of the search carried out of resources using the HOMER system.
