The availability based tariff (ABT) structure introduced by Government of India established inter region grid discipline through Central Electricity Regulatory Commission Regulation 2009. Using this regulation the over /under injection by the generators during off-peak/peak hours are discouraged and the frequency is maintained within a range amongst five regional grids of India. This work follows...
The national energy generation resources ofPakistan are becoming insufficient due to increased demandof electrical energy. The country is suffering from acontinuous shortfall of thousands of megawatts especially insummer when the demand increases many folds. Theadditional support to the national grid by means of smallhydro projects on canals can be much beneficial. A techniquecan be devised through...
Increased environmental and economic concerns have set the stage for an increase in the fraction of electricity supplied using renewable sources. Recent advances in wind prediction offer hope that reduction in the uncertainty of wind availability will lead to an increase in its value. Model based methods that predict future wind availability and then optimize local generation have been seen to be...
The main objective of this paper is to develop software model for reliability analysis using Availability Based Tariff (ABT) method for state grids to maintain the reliability and quality of the power system. For maintaining the grid discipline Availability Based Tariff (ABT) method has been followed. It is the frequency linked tariff system. ABT has three part tariff system such as fixed charge,...
The use of oxygen concentrators for the supply of medical oxygen in developing countries is increasingly becoming an alternative to conventional compressed gas cylinders, which are expensive to refill and logistically challenging to transport. Oxygen is important for obstetric, surgical, and an aesthesia care, as well as for the effective management of many diseases including severe sepsis, malaria,...
In the deregulated power systems, the interruptible load management (ILM) is widely used as an effective measure to ensure reliability and mitigate the market price spike. A critical issue is the incentive paid to the consumers to participate in the ILM. This paper addresses the quantification and allocation of ILM's benefit from mitigating the wholesale price spike. This benefit is calculated within...
Rapid expansion of rural cell phone subscriber base in India is facing some tough challenges in getting the stable back up power for cell sites. Grid power availability is very poor and use of diesel generator is turning out to be expensive with heavy fuel and transportation costs. Use of alternative energy provides a long term viable solution. Solar-wind hybrid power generation system was installed...
In this paper, the need of suitable mechanism for wind power trading is discussed and the tariff rate decided by state electricity commissions is compared with the rates a wind generator can avail if it opts for unscheduled interchange rates/ day ahead tariff. A Wind generator must buy or sell energy production deviations as per prediction errors when they bid in day-ahead energy markets. A suitable...
For every state utility in India, along with state owned generation there are two major sources of power available to fulfill the load demand. They are, Central Govt owned generation i.e. central sector generation and power purchased from power trading market. For optimum scheduling, additional sources of power need to be incorporated in the generation scheduling algorithm, along with their individual...
The objective of this research was to determine the adequacy of the rule-of-thumb reserve margin for Indiana's electricity generation system and the adjustment of the reserve margin. To achieve the objective, a statistical model is constructed to evaluate system reliability. Monte Carlo Simulation is applied to build the capacity availability probability distribution as the generation model. Hourly...
A future perspective micro-grid with a medium-term prediction for 2030 is described. The present state of intentional islanding is briefly reviewed. Distributed Generators (DGs) and Electric Vehicles (EVs) to sustain the local distribution system in the event of interruption of supply are considered. Projections regarding their availability are presented and different penetration scenarios are addressed...
The European Union has committed itself to sourcing 20% of its energy from renewables by 2020. Britain's excellent wind resource is expected to make a significant contribution to this target, not least from Scotland and the north of England. However, exploitation of this resource requires appropriate and timely development of the GB electricity transmission system. This depends on appropriate market...
This paper provides a high level overview of the single electricity market (SEM) that has recently been established for the Island of Ireland. The authors of this paper have been involved with this market liberalisation programme since its beginning and provide specialised insight into the development and initial operation of this new market. This new electricity market was especially significant...
This paper investigates availability of Demand-Side Management (DSM) considering Flexible, Reliable and Intelligent Energy Delivery System (FRIENDS) proposed by the authors. The proposed DSM is based on a Real-Time Pricing system (RTP) executed by owners of Quality Control Centers (QCC) in FRIENDS, which are facilities allocated close to consumers. More specifically, QCC owners procure electricity...
