Scheduling of Talcher stg II Clause 6.4 of IEGC The national interconnected grid is divided into control areas, like Regional ISTS, States, DVC, etc. where the load dispatch centre or system operator of the respective control area controls its generation and/or load to maintain its interchange schedule with other control areas whenever required to do so and contributes to frequency regulation of the synchronously operating system. The Load Despatch Centre of a control area therefore is responsible for coordinating the scheduling of a generating station, within the control area, real time monitoring the station’s operation, checking that there is no gaming (gaming is an intentional mis-declaration of a parameter related to commercial mechanism in vogue, in order to make an undue commercial gain) in its available declaration or in any other way revision of availability declaration and injection schedule, switching instructions, metering and energy accounting, issuance of UI accounts within the control area, collections/disbursement of UI payments,outageplaning etc.

SRLDC as the control area: Benefits Control area definition An electrical system bounded by interconnections (tie lines), metering and telemetry which controls its generation and/or load to maintain its interchange schedule with other control areas whenever required to do so and contributes to frequency regulation of the synchronously operating system. Minimal to and fro co-ordination between RLDC’s and SLDc’s in case of scheduling process involving surrender,recall etc. Less time in to and fro communication

Right from planning to implementation Tal II is apart of SR system. Only geographically located in ER system SR boundary is upto Talcher AC I/C & Jeypore end of Gazuwaka line In analogy to 6.4.2c(iii) of IEGC and SoR of IEGC 2010 in para 41.13, the control area jurisdiction of Talcher-II shall be with SRLDC as more than 50% share is to SR constituents.SoR of IEGC 2010 In case of Open Access transaction also the nodal RLDC is that of importing region. On same Anology SRLDC is nodal agency for Talcher-II It plays a vital role in the LGBR of SR SPS already in place for eventualities like unit /pole tripping. Present system is working fine for over 8 years. Scheduling of Talcher stg II
