Документ Відкритий доступ Aggregation price models for Microgrids with distributed energy resources(КПІ ім. Ігоря Сікорського, 2022) Denysiuk, S.; Derevianko, D.; Bielokha, H.; Zaichenko, S.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 Distributed Generation sources to optimize their operation. While implementing variable pricing models the aggregator should take into account characteristics of different Distributed Energy Resources (DER) (diesel engines, gas turbines, fuel cells, solar panels, small hydropower plants and wind turbines) and LCOE for each type of DER to stimulate each local electricity market participant separately. The system Microgrid using three diesel generators and the option of replacing one generator with a solar electric and wind generator installation was considered.Документ Відкритий доступ Peculiarities of lightning protector of ground solar power plants in Ukraine(КПІ ім. Ігоря Сікорського, 2020) Derevianko, D.; Danilin, O.; Hilevych, K.One of the most promising and developing areas in the energy sector is development of renewable energy sources. Among others technologies of solar energy and wind power are the fastest to develop in the sector. That is why solar power plants are under discussion in this paper. The increase in the Solar Power Plant’s capacity in Ukraine from 2018 to 2020 reached 7 times. Problems that may interfere with the functioning of the ground solar power plants are considered as this technology covers large areas of land and is on the 1st place on the amount of lightning strikes among the renewables. Ways to solve the problems associated with the damage from direct lightning strikes for ground solar power plants are discussed in this paper. Active and passive types of lightning protection for inland solar power plants are investigated and their modeling is carried out and presented in this paper. The measures proposed in this paper based on the implementation of an active lightning protection system ensure uninterrupted operation of the ground solar power plants, avoid reduction of service life and unnecessary economic costs for the replacement of damaged photovoltaic modules, reduced costs related to complexity of installation of passive system in comparison to active lightning protection system.
