Abstract

In  this  paper,  a  structural  decomposition  analysis based  on  an  input-output  framework  has  been  developed  to examine the factors, which affect the economy-wide CO 2  emission changes due to the introduction of carbon tax in the Indonesian power sector during 2011-2030. There are three major components that affect the total economy-wide change in CO 2  emissions, i.e., fuel mix-, structural-, and final demand- effects. The results show that, the CO 2  mitigation under the carbon tax of US$200/tC would be 20.5 times higher than that with the carbon tax rate of US$5/tC.  The fuel mix effect is found to be most influential in reducing the CO 2  emission during the planning horizon under all of the carbon tax  rates  considered  and  is  followed  by  the  final  demand-  and structural-effects.

Abstract

This study analyses the CO2 emission implications of considering energy tax in power sector planning for the case of Indonesia. There are four energy tax rates considered in this study i.e. US$0.5/MBtu, US$1.0/MBtu, US$2.0/MBtu and US$5/MBtu. Furthermore, this study also analyses the decomposition of the economy-wide CO2 emission changes due to the carbon tax rates by using an input-output model. The implications of energy tax on utility planning would bring the sytem more efficient because more energy efficient technology power plants, such as CCGT, would be selected, while in the case of environmental implications, CO2 emissions would be reduced. The results show that there is a significant change in the annual CO2 emissions if energy tax rate of US$5/MBtu is introduced. There are three major components that affect the total economy-wide change in CO2 emissions, i.e., fuel mix-, structural-, and final demand- effects. The results show that the fuel mix effect is found to be most influential in reducing the CO2 emission during the planning horizon under all of the energy tax rates considered and is followed by the final demand- and structural-effects.

Abstract

Electricity  supply  has  gained  importance  with  the increase of electricity demand in the world. The energy that the sun can accept forever provides great convenience for electricity generation. In regions where the suns rays are steep, it is easier to generate  electricity  from  the  solar  energy,  whereas  in  regions where  the  suns  rays  are  horizontal,  the  electricity  production from  the  solar  energy  remains  at  a  lower  level.  In  this  study, Istanbul and Adana are compared in the northern and southern regions  of  Turkey.  These  two  cities  were  examined  for  daily sunshine  periods,  daily  and  monthly  radiation  amounts.  The effects of air temperatures and sunshine durations on the average radiation amounts have been investigated. The province of Adana has  an  annual  total  of  1568.49  kWh,  whereas  the  province  of Istanbul  has  a  total  of  1327  kWh  radiation.  When  the  annual sunshine  periods  are  examined,  it  is  97.13  hours  in  Adana  and 78.99 hours in Istanbul. It is seen that less electricity production can  be  done  year  round  in  Istanbul  province  and  the  hourly production is more than that in Adana when compared to sunrise times.  When  the  average  annual  temperatures  are  examined, Adana  province  is  19  °C  and  Istanbul  province  is  13.8  °C. Although  the  province  of  Istanbul  has  a  lower  average temperature, it has been found that it has a higher yield than the province of Adana.

Abstract

A  primary  requirement  of  a  modern  electric power system is reasonable ability to satisfy the customer load requirements. Electric utilities involve generation, transmission, and distribution facilities each one of which contributes its own inherent  difficulties  to  the  problem  of  satisfying  customer requirement. A power system should be designed and expanded the facilities  in  order to  perform  its  intended function  with a reasonable risk. With increasing the electrical energy demand and the potential of disruption that may occur in the system, the distribution  system  must  have  high  reliability  and  continues supply to customer. In this case, the reliability of the distribution system needs to be evaluated by monitoring and analyzing the level of distribution system failure in a certain period of time.  A study  on  a  practical  distribution  system  with  application  of automatic  circuit  reclosers  (ACRs)  which  plays  an  important role in enhancing the reliability index of system is presented. The reliability index assessment analyze the reliability index of the existing system before and after application of ACRs. From the simulation  point  of  view,  the  system  average  interruption frequency  index  (SAIFI)  is  about  19.43%  or  decreased  the failure frequent event from 11.4 failure/ customer.year to 9.25 failure/customer.year);  while  the  momentary  average interruption frequency index (MAIFI) has decreased from 6.72 failure/customer.year to 5.05 failure/ customer.year, or increase the reliability index of about 24.85%.

Abstract

Electrification of the transportation is taking place at  an  accelerated  rate.  Even  though,  electric  vehicles  (EV) evidently bring numerous environmental and economic benefits, their impact on power systems should not be overlooked. It has been identified that EV load characteristics can significantly affect power system voltage stability and small signal stability. Hence, it is important to consider mitigating of stability impacts right from the  planning  stage  of  bulk  EV  charging  stations.  However, unavailability of suitable stability evaluating indexes that could fit into planning algorithms is a hindrance. This study proposes two computationally  efficient  indexes  to  compare  stability  status  in different  planning  options.  The  developed  indexes  have  been tested, verified and utilized in a multi objective planning algorithm to  identify  a  comprehensive  solution,  which  satisfies  the  grid operator,  EV  customer  and  the  charging  facility  investor optimally.

Abstract

Indonesia  is  blessed  with  abundant  renewable energy resources. Nevertheless, they have only been used to cover about 5% of the total national energy demand.   To optimize their utilization, the government has to make and implement a policy that will encourage PLN costumers to help increase their on-grid power supply capacity. This policy will provide benefits for islands that are already equipped with PLN power grids. This paper uses Solar  Power  Plants  and  household  costumers  as  models  to calculate  potential  on-grid  power  increase  which  can  be contributed by PLN costumers. A two-way power meter is used to replace the currently used one. This model will be applied to the  conventional grid to demonstrate the compatibility that show how it is applicable even without upgrading the conventional grid to become   smart grid system. The result shows that customers can participate significantly through the flow of their excess energy to grid

Abstract

The dependency of relying on switching power supplies is increasing and in more demand these days to present superior efficiency as it’s compared to conventional linear power supplies. The main target in any type of photovoltaic power system is to increase the efficiency rate of the PV arrays; and as a result power systems that depend on a set of PV arrays have a priority to track the maximum power point MPP to extract the ultimate maximum power from the set of arrays. One of their important characteristics is the ability to provide step-up in the form of Boost converters, step-down in the form of buck converters, and utilized in the sense of inverting. In this research paper we will delineate a sector of the various sort of switching regulators used in dc-dc conversion especially the boost converter. In addition a review of the control techniques for these converters were touched based.

Abstract

Solar and renewable plants are increasingly being added to national grids. One technical drawback of renewable generators is that they tend to cause a significant harmonic distortion of the current and voltage waveforms. The harmonic distortions are amplified when the natural resonances of the grid interact with the injected harmonics from the power electronic based PV generation. A sustained harmonic distortion can lead to equipment failure, reduced plant output or a complete plant shutdown. Therefore, it is important to study harmonic interactions and resonance issues using fully detailed EMT models before the commissioning of a renewable plant. This paper outlines important features of modelling solar converters for the use of harmonic and resonance studies.
