Harmonics in power system disturbs the quality of energy supplied to load, increased energy losses and reduce the reliability of the power system. In some cases, the large power converter systems produce not only typical harmonics but also a significant amount of inter harmonics which can significantly deteriorate the quality of power supply voltage. Inter harmonics are those components of current or voltage waveform which are not integer multiple of fundamental frequency component. Since poor power quality cause losses in power system that's why researchers are working to find techniques to estimate and control the harmonics in power system. Singular value decomposition approach is an ideal technique to estimate harmonics in power system located far away. Since in most of the cases, power system produce over determine equations which can easily be solved using SVD for optimal solution. Singular vector decomposition, SVD is really a mathematical method to lessen a dataset containing an extensive number of qualities to a dataset containing fundamentally less values, yet which still contains a huge portion of the variability introduce in the first information. SVD investigation brings about a more reduced representation of correlations, particularly with multivariate datasets and can give knowledge into spatial and temporal variations exhibited in the fields of data being analysed under different circumstance. Similarly traditional least square method is also one of the most prominent method to estimate the line of best fit. This research work will show the analysis of said techniques to find the optimal approximation of noisy and distorted wave form. To investigate effectiveness of said techniques; simulations will be carried out in MATLAB with same parameters.","PeriodicalId":404870,"journal":{"name":"2014 International Conference on Energy Systems and Policies (ICESP)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114331677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the buildings, energy efficiency can be achieved using the insulation materials, improved architectural technique, and modified construction methodology. Energy demand to operate buildings must be reduced to develop energy efficient and sustainable buildings for the future, without compromising the living comfort, performance, and services. The architecture, design, and orientation of building are altered to introduce energy efficient and sustainable design in commercial, residential, and industrial buildings. Observations and experiments were carried out on four existing buildings and a model was studied and compared based on orientation, construction materials used, type of construction, and architectural techniques. The results show that, using Alpolic Cladding and double layered windows at outer face of buildings gives 8% more thermal efficiency than the ordinary construction. The cavity wall construction enhances the energy conservation of the building by 6% as compared to traditional construction of block masonry. The model studies show that using cavity wall and Structural Concrete Insulated Panel (SCIP) as cladding/infill walls in frame structures can reduce the energy demand of the building upto 3%. Building orientation, architecture, use of latest energy efficient materials, and enhanced construction techniques contribute significantly towards energy efficient performance of buildings.","PeriodicalId":404870,"journal":{"name":"2014 International Conference on Energy Systems and Policies (ICESP)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121555467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To generate steam and heat oil, these industries use natural gas and heavy furnace oil. Natural gas is contributing 43.2% & Oil is contributing 34.12% in Pakistan's energy mix. But, currently the country is facing extreme natural gas shortages and Oil prices in the past few years have exponentially increased. As an alternate source of energy in Pakistan, solar energy can be used as the geographical location of Pakistan suits harnessing solar energy. This paper presents the designing and modeling of solar concentrator using Fresnel mirrors to provide an alternate source for steam generation and hot water supply for the industry. Solar irradiation data for the concentrator at different solar angles is simulated using MATLAB to calculate an optimal angle and amount of solar irradiation present in the region and an angle of 30 degree was selected. To determine the temperature of the concentrator laboratory scale model on area of 2m2 was set up and series of experiments were performed and a temperature difference of 150°C was achieved at the exit of evacuated tube. COMSOL was used to simulate heat exchanger and steam at temperature 110°C was obtained during simulation.","PeriodicalId":404870,"journal":{"name":"2014 International Conference on Energy Systems and Policies (ICESP)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131199322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Factors like photovoltaic technological developments, cost reduction, ease of grid integration etc. made it a viable option for power generation. Pakistan existing electric system is highly dependent on imported fossil, especially oil. As indigenous resource, most expectations are from Thar's lignite resources to fulfill country future energy requirements. But due to coal low quality and high overburden to coal ratio, the option is not economical with current prices. In addition, huge financial requirements are also hurdles to initiate the exploration even after passing more than 20 years of its discovery. Efforts have been made in this paper to assess possible role of renewable in general and solar resources particular, in Pakistan's future electric system. For this purpose, the country electricity demand has been forecasted till 2050. To account for infrastructure requirements the country has been divided into 17 sub-regions. A case of supply has been considered where demand is fulfilled only by renewable generation. The system has been simulated using CPRESS1 at time scale of “hour” to incorporate the intermittency of renewables. From analysis, it is found that more than 85% of total forecasted 587 TWh electricity demand can be fulfilled with renewable by maintaining strict utilization factor. In total supply system, a contribution of 25-30% comes from solar resources. The value of 100% renewable supply is also achievable either to increase biomass potential and/or making compromise on the economics of solar by relaxing its utilization factor. The solar resources served major part of pumping load's demand, therefore their contribution toward system stability and facilitating wind integration is also noteworthy","PeriodicalId":404870,"journal":{"name":"2014 International Conference on Energy Systems and Policies (ICESP)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132230527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electricity supply shortfall, exhausting extractable oil and gas resources, extensive reliance on imported crude oil and climate change are major drivers for the shift towards renewable energy alternatives. Since high electricity generation cost of renewable energy technologies remain a major hurdle, it is countered through introducing RE support and policy measures such as Tax Rebates, Capital Subsidies, Feed in Tariff and Net Energy Metering policies etc. Pakistan introduced its Feed in Tariff support policy for integration of renewable energy into the national grid. National Electricity and Power Regulatory Authority (NEPRA), a regulatory body, set two different tariffs for solar PV FiT projects in northern and southern regions of the country based on varying solar irradiation. In the light of tariff set by the regulatory authority and simulations performed with Polysun 6.2, for an identical nameplate capacity solar PV projects in different cities, an economic comparison in terms of Payback Period and Net Present Value has been conducted to assess the most suitable location for solar PV installations in Pakistan, as per which Peshawar turned out to be the most financially lucrative location for implementation of solar FiT projects in Pakistan.","PeriodicalId":404870,"journal":{"name":"2014 International Conference on Energy Systems and Policies (ICESP)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133027348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Pakistan, most of the power generation takes place through burning of fossil fuels and hydropower. Hydropower is renewable, clean, and cheaper. However, the high capital cast, and reliance on imported technology has hampered a steady progress in this field. Diversification of energy sources is indispensable for a sustainable progress in energy sector Renewable energy sources other than hydro sources such as solar, and wind are available in abundance in the country. Wind and solar energies seem to be very promising due to corresponding well developed technologies which can be easily supported by indigenous industries. Fortunately, Pakistan lies in the region where average daily radiation falling on horizontal surface ranges from 4.2 kWh/m2/d to 5.54 kWh/m2/d[1] and it is considered ideal for solar thermal applications. Pakistan is slowly moving to use these renewable energies on smaller scale but on larger scale renewable power plants are yet to be materialized. This study is an effort to explore the working and effectiveness of parabolic trough solar energy system. Solar energy system is designed with four main components namely steam turbine, parabolic trough, heat exchanger and a condenser. The main intent in this research work was to produce steam with the help of parabolic trough system by utilizing solar energy and develop a proof of concept prototype to demonstrate that parabolic solar collectors can be used for power generation. It took approximately 45-55 minutes for 2 liters of water to boil within the receiver tube of the parabolic trough. The modeling, testing and fabrication of parabolic trough have shown convincingly that the solar energy can be utilized for power production.","PeriodicalId":404870,"journal":{"name":"2014 International Conference on Energy Systems and Policies (ICESP)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133224105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
