Abstract

This paper describes a practical approach to identify nodal price compensation payment for nodal consumers willing to reduce their energy consumption (consumers’ demand response). The implementation of a nodal reliability service pricing is based on contingency assessment of N − 2 order for transmission lines. A representative annualized demand curve is used to reflect the system’s operation condition by seasons. Such curve is used to access the nodal reliability impact trough a whole year in order to determine back-payments (incentive payment) to users for service interruption. The IEEE_RTS 24 nodes system is used to implement the proposed approach.

Summary

Introduction

Electricity restructuring, called deregulation, enhances competition among energy suppliers and gives the consumer the ability to choose an electric supplier based on a CrossCheck date: 18 November 2016. The nodal identification of interruptible loads is based on the expected nodal energy not supplied (ENENS) and a structural decomposition of the system reserves in order to improve the loss of load probability (LOLP) reliability index The method sets both a tariff for high nodal reliability performance and a ‘‘money back’’ payment incentive for interruptible loads. It offers users on DR programs a transparent, simple way to calculate their expected amount of reimbursements based on their level of service interruptions.
