TL;DR: In this paper, the authors investigated the market structure and competitiveness in the Wholesale Electricity Market in India (WEMI) and suggested that market power of firms may be part of the reason for the increase in electricity prices in WEMI.
TL;DR: In this paper, a new formulation to maximize the operational profit of a micro grid connected hybrid system having wind farm and pumped storage unit for a day ahead electricity market in a frequency based pricing environment is presented.
TL;DR: This paper discusses an unconventional concept- tariff linked to frequency which has been introduced in India at the inter-state level through the three-part tariff for central generating stations, the so called availability based tariff (ABT).
Abstract: This paper discusses an unconventional concept- tariff linked to frequency. This new concept has been introduced in India at the inter-state level, starting from mid 2002, through the three-part tariff for central generating stations, the so called availability based tariff (ABT). In this scheme overdrawals are costly when the grid is short on generation, and are cheap when the grid has surplus generating capacity. Similarly any oversupply is paid for at a high rate when frequency is below 50.0 Hz and at a low rate when the frequency is above 50.0 Hz. Underdrawal and undersupply also get the same treatment.
TL;DR: A real-time fuzzy inference based automated irrigation controller implemented in LabVIEW, that utilizes the data logged from the sensor network and communicated using GSM/GPRS module is presented.
TL;DR: In this article, a model for price based automatic generation control is presented which will prevent unintended unscheduled interchanges among the participants, which can improve the control of frequency and bring down the UI obligation of participants.
Abstract: The Availability Based Tariff (ABT) mechanism has been introduced in Indian system mainly to ensure grid security and to deal with grid indiscipline prevailing in the system prior to its introduction. Unscheduled Interchange (UI) charge - one of the components of ABT, acts a mechanism for regulating the grid frequency. At the same time, this mechanism offers opportunity to participants to exchange as and when available surplus energy at a price determined by prevailing frequency conditions.
Although the underlying principle on which UI mechanism of ABT operates is quite different from the conventional load frequency control mechanism, it can still be viewed as a price based secondary generation control mechanism. Presently, the generators are responding to price signals manually. In this paper, a model for price based automatic generation control is presented. A modified control scheme is proposed which will prevent unintended unscheduled interchanges among the participants. The proposed scheme is verified by simulating it on a model of isolated area system having four generators. It has been shown here that such control mechanism, if adopted by all generating stations, can improve the control of frequency and bring down the UI obligation of participants.
