The Demand Response Measure

what is demand response?

Demand Response (DR) is the promotion to encourage consumers to change their usage patterns in response to price electricity at different times. This is for reducing power peak demand which will benefit for the management of the electricity crisis and enhance energy security in both the short and long term.

Demand Response Measures to Reduce Power Peak in an electricity crisis of the past

During the years 2013-2014

April 2013	Campaign to reduce energy consumption across the country to resolve gas crisis in Yanada resource by the cooperation of industry and the public sector.
December 31, 2013 - January 20, 2014	Open for voluntary application to reduce the electricity demand from the crisis of the Yanada resource. This is targeted for 200 MW but It actually gains 70 MW.
May - July 2014	Campaign to reduce energy consumption in the south region to resolve gas crisis in JDA resource by the cooperation of industry and the public sector.
December 31, 2013 - January 20, 2014	Open for voluntary application to reduce the electricity demand from the crisis of the JDA resource with electricity energy rebate. This is targeted for 247 MW but It actually gains 48 MW.

In the years 2015

April 2013	Campaign to reduce energy consumption across the country to resolve gas crisis in Yanada resource by the cooperation of industry and the public sector.
December 31, 2013 - January 20, 2014	Open for voluntary application to reduce the electricity demand from the crisis of the Yanada resource. This is targeted for 200 MW but It actually gains 70 MW.
May - July 2014	Campaign to reduce energy consumption in the south region to resolve gas crisis in JDA resource by the cooperation of industry and the public sector.
December 31, 2013 - January 20, 2014	Open for voluntary application to reduce the electricity demand from the crisis of the JDA resource with electricity energy rebate. This is targeted for 247 MW but It actually gains 48 MW.

Types of Demand Response

DR can be categorized according to the type of response mechanism into two varieties.

1. Reliability-based Demand Response

It was Load demand response form at a time when the reliability of electricity system is low or unusual s or emergency event that risk to the stability of the power system occurs. This can be set the compensation price measure to suite the participated power user performance as follow;

- Direct Load Control Measure

- AutoDR to EMS Measure

- Curtailable/Interruptible Tariff Measure

- Emergency Demand Response Program

- Demand Bidding/Buyback Program

- Capacity Market Program

- Standby Generator Measure

- Energy Storage Measure

- Ancillary Service Measure

2. Price-based Demand Response

It used price mechanism for loading demand response. The high cost of electricity is set when the high electricity demand or a risk events that affected to the power system occurs. This aims to encourage the consumer to reduce electricity consumption or shift used time to the cheaper electricity prices period. The measures are as follow;

- Time of Use Rates Measure

- Critical Peak Pricing Measure

- Peak Time Rebate Measure

- Real Time Pricing Measure

Demand Response measures taken in the future

Currently, the Ministry of Energy has conducted research and implement the pilot measure on Direct Load Control and AutoDR to EMS measures, which makes more efficiency to control the power consumption and reduce the growth of power plant construction. The pilot was conducted in the industrial, business and residential sectors, such as 100 houses in housing demand response pilot project (DR100) by the Faculty of Engineering, Chulalongkorn University, and so on.
