    Since the invention of the internet for military and academic research purposes, it has evolved to meet the demands of the increasing number of users on the network, who have their scope beyond military and academics. As the scope of the network expanded maintaining its security became a matter of increasing importance. With various users and interconnections of more diversified networks, the internet needs to be maintained as securely as possible for the transmission of sensitive information to be one hundred percent safe; several anomalies may intrude on private networks. Several research works have been released around network security and this research seeks to add to the already existing body of knowledge by expounding on these attacks, proffering efficient measures to detect network intrusions, and introducing an ensemble classifier: a combination of 3 different machine learning algorithms. An ensemble classifier is used for detecting remote to local (R2L) attacks, which showed the lowest level of accuracy when the network dataset is tested using single machine learning models but the ensemble classifier gives an overall efficiency of 99.8%.

    The Electricity Security in Nigeria: Design and Analysis of 750-kV Mega Grid
    (International Research Publication House, 2020-09-01) Ademola Abdulkareem; Victoria Oguntosin; Oluwatimileyin Dare; Adesina Lambe Mutalub
    Nowadays, due to the ever-increasing global energy demand and the complex option for an individual to install renewable power generation at his/her residence, it has become imperative to operate power plants that deliver energy to transmission and distribution systems at a reduced power loss and at the same time maximize efficiency. Therefore, the need arises to construct cost-effective high transmission lines considered at Extra High Voltage (EHV) levels. In this study, the mechanical structures and electrical line parameters of a 750-kV single-circuit 4 conductors per bundle based on existing standards were designed. These EHV levels are then analyzed and the results obtained are compared with the 330kV lower voltage levels in order to extract the benefits. The implementation of the designed 750-kV grid in the Nigeria transmission system results in a significant reduction in the systems’ power losses in comparison to the existing 330-kV system.

    Total Harmonic Distortion (THD) in a Short Distribution Line of Varying Busbar Loads
    (International Academic Institute for Science and Technology, 2017-01-01) Adesina Lambe Mutalub
    In Electric Power Systems, attention is being focused on poor power quality issues which, in most cases, is caused by non-linear loads connected to the network. This often leads to waveform distortion. Consequently, harmonics at various electrical equipment that are connected to the power system are created. At this condition, the current or voltage Total Harmonic Distortion (THD) values violates the limits specified by IEEE 519-1992. This paper presents an investigation into the Total Harmonic Distortion of a short Distribution line (DL) with varied restoration energy in Megawatts. The distribution line of case study (Alagbon - Alagbon local) is between Alagbon 2 X 60 MVA, 132/33kV Transmission station and Alagbon local 2 X 15 MVA, 33/11kV Injection station, both within the same perimeter fence and located in Lagos, Nigeria. An algorithm as well as a Model circuit were developed and presented. This algorithm was applied to the developed Model circuit for Harmonic simulation using the MATLAB/Simulink platform. The resulting harmonic (second harmonic) at varying Busbar loads remained the same as shown in the results presented. Necessary discussions were made with conclusions drawn accordingly.
