A Loadability Study of 30 kV Misurata Distribution Network

الملخص

Due to the expansion of power distribution networks, the power delivered to the loads might get through corridors which limits their capability of transmitting the power. This concept is termed as the loadability. An unplanned increase in power consumption in the Libyan network, especially after 2011, led to major problems at different levels of the power network. For instance, these issues are addressed at the generation level as power shortages and load shedding while at the distribution level presented as under voltages and loadability issues. In this paper, a study of the loadability of 30 kV Misurata electrical distribution network (MDN) is carried out using the NEPLAN software. Even though the MDN is considered one of the largest distribution networks in Libya, a lack of data is found which makes an ambiguous vision about this network and the necessary developments required in the future as well as adds some difficulties to making studies. The work presents the steady state operation of MDN under the existence of the current and estimated loads up to the year 2026. The results show significant loading problems in Misurata distribution network which should be considered to avoid the anticipated future power transfer limitations. Some visible solutions are proposed toensure the optimal operation of the distribution network.
