“…Common causes in residential and industrial areas are included in the fishbone diagram of Exhibit 3. A new and important contribution to the problem is from the fast-growing segments of renewable power sources such as photovoltaic (PV) solar power panels and wind power generators (Molla and Kuo, 2020). Industrial facilities are installing renewable generation and concern for grid degradation of power quality has led to research to make the grid more resilient (Shklyarskiy, et al, 2021).…”

Advanced Metering Infrastructure (AMI) is being adopted worldwide by electric utilities because of the benefits offered by the automated meter data it provides. The utility industry has been exploring methods to best leverage the abundance of AMI data now available to maximize customer power quality and develop delivery efficiencies to reduce customer electricity rates. Utilities are required by regulations to provide power at voltage levels within a set bandwidth of the nominal delivery voltage to the customer. Variances in the voltage delivered by utilities can cause a multitude of issues for the individual customer and for the entire distribution grid system. AMI meters are capable of providing voltage data at frequent time intervals, a 1-hour interval sample and 15-minute interval sample are quite common. A DMAIC process can be developed to allow an electric utility to appropriately review and act upon the AMI voltage data available. In this paper the voltage specifications will be defined (D) and measurement (M) of data explained. Analysis (A) of the abundant data is an area of significance. Suggestions are made from the analysis to improve (I) the utility management of voltage issues and control (C) the distribution grid to better maintain within specifications.

“…The state of charge of energy storage is a critical factor to consider. Molla et al's work [4] fully considers controlling the state of charge of energy storage. At the same time, it puts forward a control model for controlling the grid node voltage and sets two inputs, namely the node voltage offset and the state of charge.…”

As part of the process of voltage regulation, a voltage stability analysis approach suitable for wind power system needs to be established. On equivalent Thevenin parameters, the ordinary equivalent black-box Thevenin method is unable to characterize the wind connection mechanism. Accordingly, this paper proposes an analytical method equivalent to Thevenin for analyzing the steady-state voltage of electricity systems with wind energy. The equivalent model is adopted in this method connected to the wind energy grid because of the equivalence of injected nowaday sources. The analytic expressions for the equivalent Thevenin parameters are then derived in two equivalent ways, and the wind connection mechanism affecting equivalent Thevenin parameters is revealed. Lastly, the enhanced IEEE 30 bus system with wind power is simulated and validated, and it is verified that the research contents of the study contents can enhance the voltage stability of Network connection point. On the other hand, the research content of this topic reduces the active power wastage of the distributed generation connection, so as to keep the balanced terminal voltage distribution.

“…Likewise, the increase in the penetration of wind energy in global statistics is large [11,12]. Recognizing the stochastic nature of the wind, the integration of the energy produced in the electrical energy network remains more problematic [13], but the development of electronics in this field has influenced the reduction of this problem [14,15]. Another study [16] found that in the case of the large integration of wind farms in an energy network, it is important to try to make the points of connection-integration scattered and not close to each other.…”

Most of the countries in South-East Europe primarily depend on fossil fuels to cover their energy demands. The paper discusses the future perspective on wind energy in the country, where over 90% of energy is generated in coal-fired thermal power plants. Given the energy crisis, that has gripped the world, the possibility of covering the increased energy demand is being studied, especially during the winter. Based on current trends on energy generation, with just symbolic participation of wind, hydro and solar energy, the potential for maximization of the use of wind energy is considered, which means the use of each identified adequate location throughout the country. The main advantage here is that the maximum energy produced by wind is during winter when demand increases. This is important to know that Kosovo faces significant heating problems and its demand is covered with electricity. Analyzes prove that the country has a generous wind capacity, which reduces to a certain extent the need to import and even enables the export of energy under certain conditions. The potential installation capacity in Kosovo is 510.9 MW, of which 32.4 MW is currently in operating conditions. From the analysis made for the current wind farm in operation, the plant capacity factor is 31.8%. The study of the results indicates a direct correlation between the increase in load during the winter season and the electricity production by wind farms, thereby, the energy demand can be sufficiently covered.
