“…This model is applicable as a test bench to further research on distributed energy management systems due to its practical computation time and proximity to a real system. Operators of microgrids can use it to plan for new installations and evaluate the existing ones by entering only the system specifications [9][10][11]13,[49][50][51].

“…Additionally, the study does not consider important factors such as AC side and network voltage control, which are necessary for system stability. Therefore, in future work, we propose to include additional data related to prosumer uptime optimization, dispatch scheduling, uncertainties treatment, AC side voltage control, and demand and weather prediction from [9][10][11]13,[49][50][51] to further improve the effectiveness of the proposed energy management system.…”

Worldwide energy shortages and the green energy revolution have triggered an increase in the penetration of standalone microgrids. However, they have limited generation capacity and are wasteful when excess generated energy is curtailed. This presents an opportunity for the coordinated operation of multiple prosumer microgrids that absorb this waste to enhance their resiliency and reliability. This paper proposes a reliable prosumer model with an inbuilt energy management system (EMS) simulator that considers the mentioned deficiencies for constructing resilient interconnected prosumer microgrids. The EMS simulator operates in a real-time dynamic environment to coordinate the prosumer components and performs flexible switching for (1) prioritizing critical load by shedding the non-critical load and (2) meeting load demand locally or from other interconnected prosumers. The EMS simulator maintains energy balance by setting limits for the battery energy storage system (BESS) to preserve energy during low generation and performs real-time monitoring. The novelty of this model lies in its simplicity and flexibility, which allows interconnected prosumer microgrids to operate in cooperation without the need for communication. The proposed model is evaluated in a post-disaster off-grid scenario using a single-phase average value model that considers reasonable computation time. The simulation results of the proposed system indicate the preservation of stored energy while maintaining critical resources beyond three days of poor weather conditions.

The development of Microgrid states the problem of choosing the optimal technologies for its composition.This paper is to present cost based demand-side management methods for the Microgrids with DistributedGeneration sources to optimize their operation. While implementing variable pricing models the aggregatorshould take into account characteristics of different Distributed Energy Resources (DER) (diesel engines, gasturbines, fuel cells, solar panels, small hydropower plants and wind turbines) and LCOE for each type of DER tostimulate each local electricity market participant separately. The system Microgrid using three diesel generatorsand the option of replacing one generator with a solar electric and wind generator installation was considered.

Features of development of electric power industry of Ukraine from the point of view of the formation of the perspective structure of generating capacities of UES of Ukraine and development of renewable energy sources (RES) are characterized. In the analysis of the problem of introduction of RES in the energy system of our country and the use of advanced tariff systems, three levels are identified: the highest level - the UES of Ukraine; middle level – regional energy companies; lower-level - local energy supply systems. It is shown that the study of choosing a strategy for better implementation of dynamic electricity prices, as well as trends in business models for local electricity markets with a combination of physical, communication, information, and business levels are relevant. The peculiarities of Microgrid development as a basic element of the functioning of local electricity markets under the condition of formation of optimal modes of generation and consumption of electricity using dynamic charging, which can provide a significant part of imbalance compensation due to the widespread introduction of RES. The article considers the formation of dynamic prices at the level of local power systems (Microgrid), which have features of both the operation and implementation of business models. The elements of the business model for the local electricity market, which is proposed for the sole owner of all generators and consumers, are analyzed when Microgrid is considered as an independent element of the local market, where a dynamic balance between supply and demand. It is determined that at the level of local energy supply systems charging must be based on dynamic models that will take into account the dynamic nature of generation and regulation of electricity consumption in the system and stimulate appropriate desired actions by the consumer. It is proposed to use the tariff calculation not for the time interval, but for the state, as well as to control the optimal levels of generation and consumption of electricity to use the reference tariff and the formation of reference profiles of generation and consumption of electricity. Modified Frieze reactive power was used to estimate the discrepancy between current and optimal power regimes. References 37, table 1.
