The Indian medicine

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.

Frequency linked pricing as an instrument for frequency regulation in deregulated electricity markets

Abstract: This paper presents the design of an automatic balance service market that can act as an effective tool for system frequency control in deregulated power systems. The proposed scheme combines the presently existing manual balancing mechanism, prevailing in some countries, with the conventional automatic generation control, within a bid-based market structure. The participants in this frequency regulation service market are assumed to be responding to frequency linked price signals sent out by the system operator. Optimization models for settlement of the regulation markets have been proposed and dynamic simulation show satisfactory performance of the market.

Decision support system for operation, scheduling and optimization of hydro power plant in Jammu and Kashmir region

Abstract: In operating a complex hydroelectric system in a competitive market the operational as well as the financial risks are high. Decision makers and operators unarmed with rigorous analysis tools and techniques could cause their organization to pay dearly for their decisions. Traditionally the main objective of the system operator was to secure a stable supply of electric power to meet the local system load demand while meeting the system physical and operational constraints. The major driving force in making operating decisions was to ensure the availability of sufficient energy and capacity to meet the system demand while also meeting the non power requirements and operational constraints. This article presents Decision support system (DSS) under Availability Based Tariff Regime for operation, scheduling and optimization of the Sewa Hydro Electric Plant (SHEP) situated in Jammu & Kashmir state of India was developed to assist the SHEP operations engineers in order to improve the operational efficiency of the Sewa hydro system and to make optimal or near optimal operational and trading decisions while meeting the constraints. Use of the software can result in significant improvements to daily energy production and revenues. The hydro power plant historical operation and production is analyzed and baseline methodology of the historical operation is established. Based on the implementation of DSS on actual project site (SHEP), the DSS has demonstrated to be stable and managed to give reliable decisions. The optimal exploitation of the available hydro resources in the State combined with the minimization of the environmental impacts would not only meet the State׳s demand, but will supply power to the Northern grid to boost the overall development of the State. Also, provide support for sustainable development.
