“…Congestion management in distribution networks refers to reducing the overloading of distribution network equipment. Due to the recent increase in distributed energy resources, overloading in distribution networks has become a major technical issue which leads to stability and security issues, uneconomic operation of the grid, damaging of network equipment, or even collapsing the grid if not mitigated on time Gupta et al (2017); Prakash et al (2017b). The traditional solutions for mitigating the congestion of distribution grids include network configuration, utilization of compensating devices, managing on-load tap changers or rescheduling the loads, and generating units Pillay et al (2015).…”

“…PV and wind have common intermittent characteristics, and their output power depends on the availability of the primary energy source, Sun and wind. This intermittency can affect the stability and reliability of power grids as the variations in Sun, and wind availability can lead to technical issues such as voltage fluctuations (flicker), which can affect the performance of voltage regulating devices Islam et al (2016); Prakash et al (2017b). The most common traditional approaches for mitigating power smoothing issues are to operate the distributed RESs below the maximum power point (MPP) limit or actively utilize load participation to minimize the output power fluctuation of the renewable generators Sukumar et al (2018).…”

Battery Energy Storage Systems (BESS) are essential for increasing distribution network performance. Appropriate location, size, and operation of BESS can improve overall network performance. The appropriately scaled and installed BESS helps meet peak energy demand, improve the advantages of integrating renewable and distributed energy sources, improve power quality control, and lower the cost of expanding or re-configuring the distribution networks. This paper investigates the feasibility of BESS for providing short-term and long-term ancillary services in power distribution grids by reviewing the developments and limitations in the last decade (2010–2022). The short-term ancillary services are reviewed for voltage support, frequency regulation, and black start. The long-term ancillary services are reviewed for peak shaving, congestion relief, and power smoothing. Reviewing short-term ancillary services provides renewable energy operators and researchers with a vast range of recent BESS-based methodologies for fast response services to distribution grids. Long-term ancillary services will provide the distributed network system operators and researchers with current BESS-based bulk-energy methods to improve network reliability and power quality and maximize revenue from renewable energy generation. The review presents a list of energy storage policies and BESS projects worldwide with a cost-benefit analysis. The challenges for deploying BESS in distribution grids recommended solutions for the implementation challenges, and future research directions are also presented.

In the context of energy decarbonization, wind farms with type IV wind turbines from various manufacturers are being massively put into operation. These wind turbines comply with the requirements of the grid codes of the countries where they are designed and/or manufactured, but do not factor in the specific features of the distribution networks of other countries to which they are connected. The study at issue involves a comparative analysis of the requirements of grid codes of different countries for the stable operation of wind turbines under standard disturbances. The Low Voltage Ride Through (LVRT) characteristic implemented in type IV wind turbine inverters makes it possible to prevent wind turbine shutdowns in case of short-term voltage dips of a given depth and duration. The calculations of transient processes indicate that wind turbines may not meet the requirements of the grid code of a particular country for their stable operation. As a result, standard disturbances will block the reactive current injection and the wind turbine will be switched off. This is often caused by the relay protection devices with a time delay of 1-2 s, which are used in distribution networks and implement the functions of long-range redundancy. Excessive shutdowns of wind turbines lead to emergency rise in the load for the generating units of conventional power plants, aggravating the post-accident conditions and disconnecting consumers of electricity. The paper presents a method for checking the LVRT characteristic settings for compliance with the technical requirements for wind turbines. To prevent wind turbine outages, one should either change the configuration of the LVRT characteristic, or upgrade the relay protection devices in the distribution network adjacent to the wind farm, or implement group or individual technical solutions at the wind farm. The performance of the proposed technical solutions is confirmed by the calculations of transient processes.

“…Demand for electricity is increasing exponentially, leading to lower grid stability and reliability [1][2][3]. To meet the demand of power generation, new options open up in terms of renewable energy generation [4]. The effective involvement of various RERsbased generation results into many advantages like better environmental policies, lowers fossil-fuel-based generation, bidirectional power flow and utility end active participation.…”
