Order:
-
These petitions have been filed by the Northern Regional Load Despatch Centre, Southern Regional Load Despatch Centre and Western Regional Load Despatch Centre with following prayers:
(a) Direct all the STUs/SLDCs to forecast their demand and make adequate arrangements to avoid dependence on Unscheduled Interchange for meeting their demand or for injecting short term surplus power, irrespective of the frequency;
(b) Direct all the STUs/SLDCs to implement automatic demand disconnection scheme as mandated in the Regulation 5.4.2(d) of the Grid Code and submit the details of the same to CERC/RPCs/RLDCs;
(c) Direct all the STUs/SLDCs/Regional entities to comply with Regulation 5.2(j) of the IEGC;
(d) Direct all the STUs/SLDCs to give their inputs to implement the grid security expert system and direct the RPCs secretariat should actively associate themselves in getting these schemes implemented in terms of NLDC letter No. POSOCO/NLDC dated 11.9.2012 to Member GO&D; and
(e) Pass such other order or directions as deemed fit in the circumstances of the case.
During the course of hearing, the representative of the NLDC submitted that in these petitions, the petitioners have enumerated the various actions taken after the grid disturbance including sending the messages to SLDCs and opening of feeders to curtail the overdrawal. He submitted that the main concern of the system operator is that there is large variation in the schedule or purchase of power by the States which is creating problems of loading of the lines and deteriorating the system parameters. He further submitted that since manual corrective actions are not giving the desired relief, the Automatic Demand Management Scheme should be implemented by all States. He emphasized that as per the Grid Code, the scheme was required to be implemented by 1.1.2011. However, except Delhi, no other State has implemented the scheme. He also submitted that the States should be directed to give the details of the feeders which should be included in the Automatic Demand Management Scheme. He further submitted that overdrawal irrespective of the frequency should be discouraged as it results in the constraints in the line loading. The representative of NLDC submitted that non-compliance of the provisions of the Regulations 5.(2)(j) and 5.3,(e) by the State constituents has also been highlighted in the petitions. He further submitted that NLDC prepared a scheme for disconnection of feeders...
