Generation dispatch with storage and renewables under Availability Based Tariff

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.
