TLDR
There are several issues which are unique to the Indian power system namely the frequency linked pricing of energy, asynchronous operation of the grid, blocked governors in state utilities etc, which have a bearing on the generation dispatch which determines the energy availability and cost.Abstract:
There are several issues which are unique to the Indian power system namely the frequency linked pricing of energy, asynchronous operation of the grid, blocked governors in state utilities etc. Each of these has a bearing on the generation dispatch which determines the energy availability and cost. In this work we study the implications of these issues on generation dispatch from first principles. The adverse effects of load prediction error and wind prediction error on dispatch and the utility of storage to mitigate them have been thoroughly analyzed.read more

Economic-emission load dispatch in renewable integrated system under availability based tariff (ABT) environment
TL;DR: In this paper, a load dispatch model based on ABT is presented, where any unscheduled interchange (UI) from generating units, which helps in maintaining nominal frequency on the grid, invites higher incentives.

A bio-inspired approach for probabilistic energy management of micro-grid incorporating uncertainty in statistical cost estimation
TL;DR: The MG OEM problem is solved considering three different scenarios to scrutinize its robustness in manipulating optimal operating schedules and statistical cost estimates and modified glowworm swarm optimization (MOGSO), a bio-inspired algorithm based on swarm intelligence is proposed to solve optimization functions globally in both deterministic and probabilistic approaches.

Sizing pumped storage in an ABT regime
T. Geetha,V. Jayashankar +1 more
TL;DR: It is shown that pumped storage on daily schedule has a beneficial impact on economics but increase emissions, and optimized generation scheduling with due consideration to emission factors of thermal plants is required.
