He added that the expert committee followed up its work with the Energy Committee, and followed up on the merits by reviewing documents with the relevant authorities and companies. And he indicated that the Parliamentary Energy Committee asked the Technical Committee to answer a number of questions raised by the public opinion, related to the causes of power outages, the speed of dealing with the interruption and its return, and the extent of the need to appoint a global advisor by the government to determine the causes of the interruption. The report, which was read by the expert, Engineer Muhammad Freihat, indicated that a state of fluctuation in the capacity of the Jordanian-Egyptian interconnection line was about 140 megawatts, and the fluctuation began to decline until it reached the level of 70 megawatts, and then started to rise to reach 200 megawatts. He added that as a result, coordination was established between the Jordanian electrical system with the Egyptian side for the purposes of disconnecting the line, but the fluctuation rose to 300 megawatts, which led to a voltage fluctuation from (390 kilovolts to 300 kilovolts), which posed a threat to the security of and stability of the electrical system. The report stated that the past years have witnessed cases of fluctuations on the Jordanian-Egyptian connection line since it was electrified in 1999, but the fluctuation levels were low and vanish within minutes and occur at a rate of approximately once every two years, explaining that this case and this fluctuation for the first time occurred and reached 300 megawatts, Seconds before the mass extinguishing. Freihat denied the existence of any human role or deliberate or cyber attack in the occurrence of the oscillation incident and the comprehensive power outage, because what happened is a physical condition and cannot be human-made, and the process of restoring the electric current came in an organized manner, and if there was a cyber attack, it would require several days To be able to reprogram and restore the power supply. With regard to evaluating the state of restoring the power supply, the report of the Technical Committee indicated that a state of emergency was declared in the National Electric Power Company, and engineers and technicians rushed to go to the various substations to help from within the stations in restoring the power in coordination with the Monitoring and Control Center. The restoration of the electric current was initiated and problems appeared, but the restoration process succeeded from the Jordanian-Egyptian interconnection line, as an alternative plan to the return plan. Aqaba stations were electrified, and the electricity was restored in succession, and the response speed was reasonable. The report emphasized that due to the lack of sufficient experience for this type of specialized studies, there was a need to appoint a global consultant, and the committee recommended that this phenomenon be studied, the use of information for the Jordanian and Egyptian networks, and the means and alternatives that must be found to work on the fading of this phenomenon when it appears and the development of an operational protocol How to deal with it, and it is globally available to operators of electrical systems through global expertise houses. The report also indicated that the “CESI” company, which the government hired, is one of the companies with high experience in the field of specialized technical studies and has previously conducted several studies for the National Electric Power Company, which is known to the committee. The local company also benefited from the international company’s expertise in raising the efficiency of its workers. In its studies, he explained that it is a neutral company with a good reputation and does hundreds or thousands of studies annually. The Technical Committee recommended that the global consultant “the company” conduct an analytical study of the oscillation phenomenon and find out its causes, and conduct a study of operational alternatives to curb the oscillation phenomenon when it appears and indicate its feasibility, such as operating diesel units and additional gas units and a feasibility study for adding any equipment or devices to the Jordanian electrical system , emphasizing the need to develop special operational instructions to address the oscillation condition. The committee also recommended increasing coordination and joint work with generation companies in natural and emergency situations, and informing the system operator, “the operating room / the National Monitoring and Control Center” about the locations of renewable energy plants “solar and wind” and large and medium distribution stations, and expanding by conducting an operational study when one of the elements exits. The electrical system, and the continuous assurance of providing the rotating reserve at all times and according to the actual ability to respond to the existing obstetric units. And she called for working to find advanced software for forecasts of production of renewable energy plants, to make forecasts more accurately, and to link them to weather information and other factors, with the need to constantly update them and to check the work and readiness of diesel generating units periodically, which are used in the event of any emergency such as comprehensive extinguishing, and restoration Considering plans for rebuilding and rebuilding the electrical system and defensive plans working on the electrical system and amending them according to the needs and requirements of the system. It also stressed the need to train operational cadres in specialized topics internally and externally, to raise the skills and capabilities of operators, and for the Energy and Minerals Regulatory Commission to raise the level of monitoring, follow-up and supervision of the sector companies and continuous verification of the performance of these companies, their continued readiness for all circumstances, and the continuous assurance of achieving performance standards different from these companies. For their part, the deputies praised the efforts made by the voluntary technical committee represented by experts, Engineer Muhammad Freihat, Engineer Ghaleb Al-Beik, Engineer Ali Al-Malkawi and Engineer Mowaffaq Hmeidat, and the results and recommendations it reached in its report, with some comments on the report.
