Integrated strategies for load demand management in the state of Tamil Nadu [articol]

Abstract

Electricity is in crisis state of demand in the state of Tamil Nadu. The state is in need of a proper power management planning. This paper aims at recommending and focusing the strategies to meet such load demand, for the period of 30 years, from 2015-2044. Two strategies are proposed namely, increasing generation capacity through Generation Capacity Expansion Planning (GCEP) and by reducing the load demand through Demand Side Management (DSM). Both strategies were analyzed With Pumped Storage System (WPSS) and With No inclusion of Pumped Storage System (WNPSS). Renewable Energy Sources (RES) opted as a future candidates with different penetration levels via Business-As-Usual RES (BAURES), Optimum RES (OPRES), High RES (HRES) as Scenarios in GCEP. In DSM, Load Management Programme (LMP) and Energy Reduction Programme (ERP) were analyzed as Scenarios. For all Scenarios Reliability index Energy Not served (ENS) is a deciding factor. Wien Automatic System Plan-IV (WASP-IV) is utilized for attaining accuracy on calculations and observations, MATLAB is used for instant simulations. Pollutants of Carbon-di-oxide (CO2) and Sulphur-di-Oxide (SO2) emitted from thermal plants, Cumulative Least Present Worth Cost (LPWC) for 30 years were estimated. The best suited GCEP option is identified as OPRES with PSS and DSM is identified as concurrent implementation of LMP and ERP with PSS. Both Suited Strategies were integrated and its effects also investigated.
