Hybrid PV/FC stand alone green power generation: A perspective for Indian rural telecommunication systems

Abstract: The objective of this paper is to conceptualize and explore the renewable energy utilization in Indian rural telecom areas and development of hybrid PV/FC green power generation for various telecommunication systems e.g. base transceiver station (BTS) at telecom sites, local data transmission system, power backup for mobile charging/other appliances. The cost of the grid power generation is so high, moreover transmission as well as maintenance of grid power in remote areas is also a challenging job. The average per day grid power availability by region in India is presented. Over all fuel consumption and cost analysis of conventional and non-conventional energy is discussing in this paper. The photovoltaic (PV) system is considered as main power generating source for supplying the telecommunication equipments and FC is considered as secondary source. The operating parameters of various types of fuel cells are presented, in which proton exchange membrane fuel cell (PEMFC) is considered for power backup supply in place of energy storage system (ESS) due to its high power density in telecom applications. The modeling and analysis of PV and PEMFC based systems have been done using MATLAB Simulink environment.

Measuring the Benefits of Delayed Price-Responsive Demand in Reducing Wind-Uncertainty Costs

Abstract: Demand response has benefits in mitigating unit commitment and dispatch costs imposed on power systems by wind uncertainty and variability. We examine the effect of delays in consumers responding to price signals on the benefits of demand response in mitigating wind-uncertainty costs. Using a case study based on the ERCOT power system, we compare the cost of operating the system with forecasts of future wind availability to a best-case scenario with perfect foresight of wind. We demonstrate that wind uncertainty can impose substantive costs on the system and that demand response can eliminate more than 75% of these costs if loads respond to system conditions immediately. Otherwise, we find that with a 30-min lag in the response, nearly 72% of the value of demand response is lost.

Duration-differentiated Energy Services with a Continuum of Loads

Abstract: As the proportion of total power supplied by renewable sources increases, it gets more costly to use reserve generation to compensate for the variability of renewables like solar and wind. Hence attention has been drawn to exploiting flexibility in demand as a substitute for reserve generation. Flexibility has different attributes. In this paper we consider loads requiring a constant power for a specified duration (within say one day), whose flexibility resides in the fact that power may be delivered at any time so long as the total duration of service equals the load's specified duration. We give conditions under which a variable power supply is adequate to meet these flexible loads, and describe how to allocate the power to the loads. We also characterize the additional power needed when the supply is inadequate. We study the problem of allocating the available power to loads to maximize welfare, and show that the welfare optimum can be sustained as a competitive equilibrium in a forward market in which electricity is sold as service contracts differentiated by the duration of service and power level. We compare this forward market with a spot market in their ability to capture the flexiblity inherent in duration-differentiated loads.

Electric power transmission and distribution systems: costs and their allocation. Research report

Abstract: Transmission and distribution costs contribute significantly to the total costs of providing electrical service. The costs derived from the transmission and distribution (TandD) system have historically comprised about 2/3 the costs of producing and delivering electricity to residential-commercial customers, and over 1/3 the total costs supplying electricity to large industrial customers. This report: (1) estimates the differences in transmission and distribution equipment required to serve industrial and residential-commercial customers and allocates to the above two customer classes the average costs of installing this equipment; (2) estimates the costs of operation and maintenance of the transmission and distribution system, and allocates these costs to the customer classes; and (3) calculates the TandD derived average costs for the two customer classes.

Power storage apparatus, method of operating the same, and power storage system

Abstract: A power storage system and method are disclosed. The system is connected to a load, a power grid, and a power generation system. When the grid is in an abnormal state, a battery is simultaneously charged with power from the power generation system and used to supply power to the load.
