Recently, a massive focus has been made on DR programs, mainly on decreasing electricity price, resolving transmission lines congestion, reliability enhancement and market liquidity improving. Basically, demand response programs are separated into two main groups named, incentive-based programs and time-based programs. The focus of this paper is on Time of Use (TOU) program and Direct Load Control...
Demand Response (DR) has gained so much importance due to its effect on load profile characteristics. The focus of this paper is on impacts of flexible load participation in day-ahead energy market, in which bulk power consumers introduce their load reduction as generation. Based on costumer's characteristics, a model is developed for the demand side participation in aforementioned program. Effects...
One of the most important missions of Smart Grid is to improve system efficiency through effective execution of Time of Use (TOU) Demand Response (DR) programs and to provide a link between consumers and electricity market in order to provide a smoother load curve. On the other hand, realization of Smart Grid in a system would be very costly. In this situation, identifying the most influential buses...
This paper contributes to the discussion about the future integration of Smart Grids in the existing energy supply system on a mostly economical and regulatory point of view. One of the main issues in this case is the increasing costs due to grid enhancements under regulated grid tariffs. On the one side a concept based on an integrative customer oriented approach is described and the new roles of...
Integration of risk factors into decision-making model for interruptible load management plays a valuable role for power suppliers to mitigate price risks and improve their profitability in electricity market environment. A decision-making model is developed for power suppliers to determine the interruptible load volume purchased from interruptible consumers. The power suppliers' tradeoff between...
In this work, we propose a multi-layered adaptive load management (ALM) system capable of integrating large-scale demand response in electric power systems efficiently and reliably. Electric power systems can be seen as a composition of multiple subsystems: power producers, load aggregators/utilities, end-users, etc. Focusing on the demand side of the system, we decompose the whole power system into...
The main benefits of implementing interruptible load management for power suppliers are from the impacts of the level of demand for electricity on spot prices. In terms of CVaR as the measuring index for market trading risk, a model of load curtailing strategies for power suppliers considering the co-utilization of the interruptible load with low price (ILL) and the interruptible load with high compensation...
The main benefit of implementing interruptible load (IL) management for power suppliers is from the impacts of the level of demand for electricity on spot prices. In terms of conditional value at risk as the measuring index for market risk, a model of load curtailing strategies for power suppliers considering the co-utilization of the IL with low price (ILL) and the IL with high compensation price...
This paper evaluates the economic effect of the Demand Response (DR) with Thermal Storage Air-conditioning (TSA) systems in electricity markets using market models based on the California Power Exchange (Cal-PX) and the Australian National Electricity Market (NEM). Our main objective is to evaluate the reductions in the Market Clearing Price (MCP) and wholesale purchase costs for all market participants...
Power planning engineers are trained to design an electric system that satisfies predicted electrical demand under stringent conditions of availability and power quality. Like responsible custodians, we plan for the provision of electrical sustenance and shelter to those in whose care regulators have given us the responsibility to serve. Though most customers accept this nurturing gladly, a growing...
In this paper the load profiles used by different entities (distribution utilities, suppliers) on the electricity market have been analyzed. Load profiles are necessary for utilities from cost of service and rate design to load management and forecasting to settlement. Principal applications for retail suppliers include pricing, cost analysis, planning and assessment of load management, load scheduling...
This paper presents a daily load response model based on the day ahead spot market prices. It can simulate an optimal expense saving on electricity based on the assumption that the total consumption is not changed. A mathematic formulation is described for the load reduction in potential hours by judging whether the actual price is higher than a certain response price. The model computation can be...
Interruptible load (IL) management as an important component of demand-side management in electricity market affects much the safe and economic operation of the power systems. The cost-benefit of interruptible load participants is analyzed in this paper. The discrete customer category is proposed to indicate the expected compensation for the blackout. This paper presents a model of IL contract, in...
Demand side management (DSM) is called demand response (DR) in the deregulated power markets. The goals of the DR programs in the electricity power markets are different and sometimes are contradicted to each other in which they could not be optimized simultaneously. Power systems regulators try to use multi criteria decision making (MCDM) to overcome with these issues. In this paper, we first review...
