The price set in electricity markets is given by the intersection of supply and demand during a given time period. The demand-side has traditionally been a price taker while the supply-side actively adjusts the output of the market clearing unit to fluctuations in consumption. Currently, there is a transition toward active demand participation that can adequately respond to market conditions. However,...
In the deregulated power systems, the interruptible load management (ILM) is widely used as an effective measure to ensure reliability and mitigate the market price spike. A critical issue is the incentive paid to the consumers to participate in the ILM. This paper addresses the quantification and allocation of ILM's benefit from mitigating the wholesale price spike. This benefit is calculated within...
This research examines optimal operation of microgrid systems. Microgrids are disaggregated from main transmission grid. Microgrids are able to integrate distributed renewable energy, take advantage of waste heat, provide higher power reliability, reduce electricity transmission loss, and decrease greenhouse gas emissions. The study considers solar power, wind power, biomass power, gas turbine, fuel...
The demand bidding/buyback is one of the demand response (DR) programs that encourages large consumers to change their energy consumption pattern and decline their peak load in return for financial rewards. This procedure is useful for both the consumers and system operator (SO) and improves market efficiency by providing the opportunity for consumers to change the market clearing price (MCP) in peak...
This paper presents a method for demand side management considering the amount of wind power generation. The intermittency of wind power may cause several problems like inadequacy of power, congestion in transmission lines, and power quality. All these technical concerns lead to financial challenges in power market. In this paper, a new concept of flexible loads following the wind farm output power...
Asymmetric information in the electricity market creates incentive for customer aggregators (ESCOs, EMCOs, LSEs, etc.) to bid strategically as new information arrives. Such companies are pooling demand to provide enhanced services to customers. Since such demand pooling companies are not defined generically, all types of demand pooling companies will be termed demand serving company (DSC) to not confuse...
In 2009, the major leaders all over the world met together for the summit on climate change, once in New York and later in Copenhagen. A clear signal is sent to public that the traditional manner of energy consumption and economic growth needs to be changed fundamentally in the near future. In order to reach the target of reducing green house gas emission, technologies such as renewable energy sources...
In 2009, the major leaders all over the world met together for the summit on climate change in Copenhagen. A clear signal is sent to public that the traditional manner of energy consumption and economic growth needs to be changed fundamentally in the near future. In order to reach the target of reducing green house gas emission, technologies such as renewable energy sources (RES) and plug-in hybrid...
The Smart Grid includes automatic responses to events on the grid, responses such as demand side management, the operation of storage devices, and the control of reactive power sources. Many of these actions will involve one party obtaining automated assistance from another party, often in a fraction of a second, and generally in time periods shorter than the settlement periods of conventional ISO...
This paper compares the methods that have been used to control frequency in the recently deregulated power system in Sri Lanka with the highly deregulated power system in Great Britain. Also it presents the proposed methods found from a literature survey that use demand side support for frequency control. It also emphasises the need of commercial and demand side arrangements in frequency control in...
The transmission system in New Zealand has not had any significant new build for some thirty years. Transpower New Zealand Limited is the owner and operator of the grid and is responsible for developing transmission proposals for approval by and independent regulator. Investment proposals have be able to demonstrate that non-transmission alternatives have been appropriately considered. As part of...
This paper discusses the demand side impact on electricity market. The demand reduction of common commodities usually leads to reduced price, and in response to the high price, demand side management may be a good price mitigation mechanism for most commodities. However, in the electricity market, electricity demand has complicated interactions with the electric network, and the demand at different...
In restructured power systems, the ISO should maintain the power system in an acceptable level of security. The amount of available transfer capability and spinning reserve are two important indicators of power system security. This paper presents a strategy for the allocation of demand response programs in restructured power system. The proposed approach is based on a multi-objective model in which...
Increasing energy prices and the greenhouse effect lead to more awareness of energy efficiency of electricity supply. During the last years, a lot of domestic technologies have been developed to improve this efficiency. These technologies on their own already improve the efficiency, but more can be gained by a combined management. Multiple optimization objectives can be used to improve the efficiency,...
Whilst significant attention is focussed on the supply side of the electricity system-from large-scale renewable generation, to new transmission technologies, significant benefits can also be achieved by improving the demand-side of the electricity system. This paper introduces CSIRO's work on intelligent demand side energy systems. This work is focussed on distributed energy control systems-decentralised...
In this paper, the amount of dispatchable responsive demand from domestic sector with different methods of charging has been evaluated and the benefits of responsive demand in order to increase the security, reducing the emissions and production cost in an intermittent system has been presented. Additional benefit; the value of wind is also demonstrated. The quantification was performed on the IEEE...
This paper investigates availability of Demand-Side Management (DSM) considering Flexible, Reliable and Intelligent Energy Delivery System (FRIENDS) proposed by the authors. The proposed DSM is based on a Real-Time Pricing system (RTP) executed by owners of Quality Control Centers (QCC) in FRIENDS, which are facilities allocated close to consumers. More specifically, QCC owners procure electricity...
