A Web Based Employee Management System

Employees are the backbone of any company. Often employee data such as personal details of employees, salary, leaves, and work allocations are managed using manual methods. These manual methods generate a lot of paperwork and make it complex to effectively manage the tasks. Most of the computerized systems proposed for employee management mainly focuses only on attendance management, leave management and salary management. This paper proposes a web-based Employee Management System solution to address the difficulties faced. The system will address the shortcomings of the existing systems and provide functions to manage employee data effectively. It will use trending technologies such as React JS, Node JS, Express JS, and MongoDB as the database which are faster and more user friendly compared to the technologies proposed in the literature. The system will use the concepts of distributed systems, client server architecture and show features of 3-tier architecture. The paper concludes that the proposed system addresses the shortcomings of the similar systems proposed in the literature but should be further improved by studying the subject area. Further research should be done to provide more features related to managing employee data and to provide a responsive design that can be accessed through mobile devices as well

Modeling Electric Vehicle Charging Station Behavior Using Multiagent System

Agent-based models(ABMs) are a type of simulation in which a large number of self-sufficient agents interact in a way that combines stochastic and deterministic behavior. Recently, there have been reestablished interests in utilizing multiagent systems (MASs) to get more granular data relating to specific conditions. MESA is an ABM framework for Python. It enables users to quickly develop ABMs with built-in core components, view them with a browser-based interface, and evaluate their findings with Python’s data analysis capabilities. This chapter depicts an ABM of a photovoltaic (PV)-powered electric vehicle (EV) charging station in a university car park modeled using MESA. The goal is to determine the preliminary requirements for PV-powered EV charging stations, which would result in increased PV and cost benefits

A Survey on Microgrid Control Techniques in Islanded Mode

Traditional power networks with generation in upstream and consumption in the downstream were controlled with centralized controls like SCADA. However, in order to facilitate the penetration of distributed generation, the concept of microgrid was popularized. A microgrid can operate both in grid-connected and in islanded modes. One of the challenges in the microgrid environment is to provide both voltage control and maintain the system frequency while ensuring the stability of the network. This paper is a literature survey focused on different microgrid control techniques with different levels of communication especially in islanded operation
