Distributed storages have been widely used and studied recently, including batteries and demand side resources, with the development of distributed energy resources (DERs). Each distributed storage has small capacity but the number of all distributed storages is very large, so it is not practical for an independent system operator (ISO) to dispatch these distributed storages directly. A storage aggregator...
Financial transmission rights (FTR) is a financial instrument for the electricity market participant to hedge the transmission congestion cost. With growing development in demand response, load serving entities (LSEs) may participate in the electricity market as a strategic bidder by offering coupon-based demand response (C-DR) programs to customers. In the LSE's bidding process, the impact of FTR...
This paper presents particle swarm optimization (PSO) based demand response (DR) methodology that helps to flatten the load curve of power distribution system. Load shifting DR technique is used to alter the load curve of the system. This article mainly focuses on the importance of DR studies for residential consumers that help the distribution utilities to reduce both peak load and their operational...
Frequency regulation in wind-powered islanded microgrids (WPIM) is critical for system stability given unpredictable dynamics from variations in wind generation and demand. Traditional methods of frequency regulation in WPIM have used classical secondary load controllers (CSLC) in a centralized approach to buffer wind generation and demand events. This study investigates the feasibility of using a...
The demand of electricity keeps increasing in this modern society and the behavior of customers vary greatly from time to time, city to city, type to type, etc. Generally, buildings are classified into residential, commercial and industrial. This study is aimed to distinguish the types of residential buildings in Singapore and establish a mathematical model to represent and model the load profile...
With the unbundling of power sector, the conflicting interests between different market entities (e.g. distribution company (DISCO) and DG owner (DGO)) can raise huge barriers for exploitation of renewable energies in an active distribution systems (ADS). To address this issue, a bilevel planning approach as a possible solution is presented in this study. The model considers the decision-making of...
Due to the development of intelligent energy management system with automatic control, the large population of residential appliances have the opportunity to be effectively utilized by load serving entities (LSEs) to reduce their operating costs and increase total profit. In practice, LSEs are promoting various demand response (DR) programs to stimulate the flexibility of industrial and commercial...
Harmonic distortion on voltages and currents increases with the increased penetration of Plug-in Electric Vehicle (PEV) loads in distribution systems. Wind Generators (WGs), which are source of harmonic currents, have some common harmonic profiles with PEVs. Thus, WGs can be utilized to subside the effect of PEVs on harmonic distortion. This paper studies the impact of PEVs on harmonic distortions...
This paper develops and presents an adaptive market-based load shedding scheme that provides options for adaptive selection of loads in real-time. Therefore an ancillary market-based system where consumers as well as system operator have options to contribute to system security can be evolved. All existing load shedding schemes are based on system operator's assessment and emphasize system security...
