Item type:Publication, Оптимално управување со токови на енергија во микромрежи приклучени на дистрибутивната мрежа(2022-09); ; Zenku, ImerThe increased penetration of renewable energy sources, as well as the higher standards for quality electricity, actualize the implementation of microgrids into the standard power system. Microgrids provide consumers with higher reliability of power supply, and characterize with lower costs and lower power losses. Microgrids consist of many different distributed generators, more interconnected consumers, batteries and backup generators, and therefore optimization is mandatory for proper and balanced operation of the microgrid. The paper analyses the problem of optimal energy management in a hybrid system (microgrid), which consists of a photovoltaic and wind generators, connected to the distribution network. Also, the microgrid includes industrial prosumers. An upgraded genetic algorithm is applied in the optimization, which takes into account the technical limitations of the installed equipment and the voltage levels in the nodes. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Optimization of Grid-Connected Microgrids with Residential Prosumers Using an Improved Genetic Algorithm(2024); With the continuous increase of the microgrids’ implementation into the power system the problem of maintaining their stability and balance arises and the necessity to adopt an appropriate energy management system emerges. This paper analyses the optimization of the grid-connected microgrid, which consists of a photovoltaic generator, a wind generator, a battery, and residential prosumers. The paper presents the application of an improved genetic algorithm, which takes into consideration the voltage levels on the connection points of the generators and the prosumers, as well as the trading with the local grid. The proposed algorithm suggests the usage of the standard genetic algorithm with the improvement in the fitness and selection process. The results of the simulation are compared with the results obtained when using a standard genetic algorithm with five different types of selection. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Оптимизација на микромрежи поврзани на дистрибутивна мрежа со примена на подобрен генетски алгоритам(2024-10); Енергетската криза со која се соочува светот денес, како и потребата од чиста и одржлива енергија, ги ставаат микромрежите во центарот на вниманието на истражувачите. Нивната работа има позитивно влијание на работата на електроенергетските системи, но поради стохастичната природа на дисперзираните генератори од обновливите извори кои се поврзани на нив, работата на микромрежите може да има негативно влијание на електроенергетскиот систем доколку не е правилно управувана. Оттука, произлегува потребата за оптимизација на микромрежите. Во овој труд ќе биде разгледан проблемот со оптимално управување со токови на енергија во микромрежа која е поврзана на дистрибутивната мрежа. Методот на оптимизација во овој труд, предлага примена на генетски алгоритам со подобрување во делот на евалуација на потенцијалните решенија и селекција на индивидуи кои ќе генерираат нова генерација. Добиените резултати се споредени со веќе докажани методи за селекција и со тоа се оправдува предложеното подобрување. - Some of the metrics are blocked by yourconsent settings
