Accurate forecasting of the electrical load is a critical element for grid operators to make well-informed decisions concerning electricity generation, transmission, and distribution. In this study, an Extreme Learning Machine (ELM) model was proposed and compared with four other machine learning models including Artificial Neural Networks (ANN), Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU).

This research presents a detailed evaluation of the total active power loss (TAPL) under different placements of photovoltaic power plants (PVPs) in the electric distribution network (EDN) IEEE 33-node. Three study cases have been conducted to serve the initial intention, including 1) optimizing both rated power and position of a PVP on selected EDN; 2) optimizing the positions of different quantities of PVPs independently to the grid with the same rated power, and 3) optimizing a sole PVP with a wide range of rated power.

Modern civilization is heavily dependent on energy, which burdens the energy sector. Therefore, a highly accurate energy consumption forecast is essential to provide valuable information for efficient energy distribution and storage. This study proposed a hybrid deep learning model, called I-CNN-JS, by incorporating a jellyfish search (JS) algorithm into an ImageNetwinning convolutional neural network (I-CNN) to predict weekahead energy consumption.

The Distribution system interconnects multiple BSSs. 802.11 standard logically separates the wireless medium from the distribution system – it does not preclude, nor demand, that the multiple media be same or different. An Access Point (AP) is a STA that provides access to the DS by providing DS services in addition to acting as a STA.

In the last lecture we looked at some high-level descriptions of key distribution and agreement schemes. These protocols cannot be used as they were stated. In implementation of the actual protocol, there are many situations one should be careful of. In this lecture, we will look at some common protocol failures that arise when trying to implement security protocols We will then look at some specific examples of security protocols

In this study, MCS is applied to compute the reliability of the nodes and the network under uncertain demand and roughness, and to determine how reliability is distributed among the various nodes of WDN, as well as assessing the reliability of the network as a series or parallel system. The effect of the resilience index on the nodal and network reliability is also assessed.

This thesis is dedicated to study how the charging behaviours of plug-in hybrid vehicles affect the local distribution network. This study focuses on two issues: the power loss and charging cost optimization. The multi-objective particle swarm optimization technique is applied to achieve the optimal charging schedule, resulting in acceptable additional power loss ratio and charging cost.
