The penetration of rooftop photovoltaics (PVs) in residential sector has a significant impact to the distribution system. The impact is not only on the technical sides but also on the economic sides. This study proposes Integrated Energy and Economic Model (IEEM) which integrates electricity generation, load profiles, economic assumptions and electricity regulation. It is developed by employing econometric spreadsheet program. IEEM investigates the effect of the PVs on the national electricity cost and electricity tariff. Spreadsheet calculation is used to determine the PVs energy production in Jakarta distribution system. Load profiles is obtained through data of residential customers in Jakarta distribution system. Both economic assumptions and electricity regulation are outlined based on Indonesian Government regulation. From the technical sides, PVs decreases the usage of distribution transformers to less than 80% of transformers load. The economic sides gives insight that PVs not only decreases the electricity sales and distribution business income, but also makes a long payback period on the distribution network investment. In further, the model calculation results show that the increasing of PVs has an impact on increasing the utility electricity cost, while residential electricity tariffs remained. This study can give a consideration for decision makers in state-owned utility to re-arrange their tariff structure and PVs policies for the feasibility of PVs projects in residential sector. This model can be applicable to any location by changing the generation, load profiles, relevant economic assumptions and electricity regulation.

In recent years, the latest technology, Gas-to-liquid (GTL) has been developed as an alternative to mineral oil. Natural ester oil is derived from vegetable oil. It is biodegradable, non-toxic, non-flammable, and has a higher breakdown voltage. Compared to conventional mineral oils and natural ester oils, GTL based oils are designed with a high level of composition and consistent performance, high purity, excellent resistance to degradation and are essentially sulfur free. In this study, GTL oil, mineral oil and natural ester oil will be compared in performance. Tests carried out for GTL oil, mineral oil and natural ester oil are tests of color scale and appearance, acid content, viscosity, moisture or water content, dielectric losses, breakdown voltage, and Dissolved Gas Analysis (DGA). Increased contaminants and free radicals cause an increase in dielectric losses and a decrease in oil resistivity. In addition, a strong correlation was found between the relative water content of oil and the breakdown voltage.

Insulating oil in distribution transformers is used as liquid insulation material and cooling winding. Distribution transformer oil from non-renewable petroleum minerals which is difficult to degrade has an impact on environmental pollution if it is unused or disposed of. This study uses corn oil from renewable natural resources for a mixture of petroleum mineral oil. The test material was made of samples from mineral transformer oil mixed with corn oil with different composition ratios, namely samples MJ0 (0: 100%); MJ20 (20: 80%); MJ40 (40: 60%); and MJ60 (60: 40%). The samples were tested for high voltage breakdown, viscosity, specific gravity and refractive index. The test results show that the mineral transformer oil mixed with corn oil to ≥40% slightly decreased in insulation strength with a voltage breakdown of 30.66 kV/2.5 mm (MJ0) to 20.93 kV/2.5 mm. Viscosity, specific gravity and refractive index showed an increase with the addition of a mixture of corn oil in mineral oil.

Nowadays, network operations, including in low voltage systems, are becoming more complex. There is a necessity to monitor the systems which could be realized using the data gathered by the smart meters. This monitoring task can be accomplished through state estimation analysis. It is hence necessary to study some factors that affect the state estimation analysis. In distribution system analysis, the unbalanced parameters of the feeders are mostly simplified with sequence networks. Shunt capacitances and grounding methods are commonly neglected. Furthermore, errors and uncertainty in measurements and power system parameters may exist. Such simplifications and imperfections are likely to affect the results of the analysis. This work covers the abovementioned issues and assesses their impact to estimation results. An AC state estimation algorithm was created in AMPL. Extensive simulations have uncovered some findings in order to obtain satisfactory state estimation in low voltage networks.

PT PLN (Persero) Transmission West Java (called PLN UIT JBB) is one unit of PT PLN (Persero) which has a strategic role in the electrical business in the DKI Jakarta & Banten. UIT JBB serves mostly VVIP and Zero Down Time area, besides High-voltage Consumers and regular consumers.Because of the service performance to customers becomes the main concern for UIT JBB, the work program must also in line with these objectives. But, the problem is in the planning of the work program itself, especially when planning the asset replacement.The current replacement planning for PT PLN (Persero) is conducted by referring to the Director Decree No. 149.K/DIR/2013 about The Replacement Criteria of The Substation Equipment which is considering the technical condition, age, and risk (environmental condition). Because there are constraints in terms of the availability of data and information about the condition of the installed equipment, the attention of annual work program is only about on the equipment which has old age and anomalies. This causes a lot of equipment will be in the replacement proposal.Therefore, to improve the service performance to stakeholder, UIT JBB makes a method in prioritizing the replacement or treatment based on the asset condition and also the substation criticality. The substation criticality is made by considering on the area or consumer that supplied by the substation according to the criteria of the UIT JBB’s stakeholder. While the asset condition themselves are obtained through the result of the combination of health index and susceptibility index. Where the health index is describing the readiness of the asset which can be obtained from maintenance results, meanwhile susceptibility index is the external factors that can be affecting the vulnerability of the equipment.This paper will discuss the method used in prioritizing the work program, especially the transformer replacement. The result of the method is the priority 1 to priority 4 of the transformer in the replacement proposal which can be used to determine which transformer must be replaced first.

The power flow method in distribution system has its own challenges attributable to its unique characteristics. Several methods have been developed to achieve a simple, fast, and precise result. One of the method is Backward-Forward Sweep (BFS) which has simple characteristic to implement in radial distribution systems. The method was improved using a new data structure and implemented in an unbalanced load with a variety of model variations. The test referred to 37 bus of IEEE radial distribution system and compare to the network without load model variation or assume all PQ load. The result shows that both performances have equally good convergence but much faster in timing computation and larger of voltage magnitude with load model variation.

The inverter using for power supply provides constant voltage, current and frequency generation advantage although there are changes in the load. However, inverter has weakness too. It will generate large harmonic. To get a high efficiency from an inverter, a sinusoidal voltage output is needed and total harmonic distortion (THD) is minimized. Several factors influence the harmonic magnitude on 1 phase inverter, namely load type and presence of filter. This study discussed about simulation of 1 phase inverter with and without LC filters, using R and RL series load type against voltage (V) and current (I) THD. The study results with LC filter and series RL load indicated THD reduction. The LC filter installation did not only affects harmonic reduction only but also output voltage and current of load.

In the present study, an attempt has been made to understand the impact of the addition of nanoparticles in natural ester oil (nanofluid) on various electro-chemical aspects. In order to stabilize the nanofluid, Cetyl Trimethyl Ammonium Bromide (CTAB) has been used as a surfactant. Various electrical and chemical analysis of nanofluid has been conducted. To analyse the impact of presence of nanoparticles on resistance to electrical stress, corona ageing of oil samples has been carried out. Results indicate higher corona inception voltage (CIV) and lesser window of discharge under phase resolved partial discharge (PRPD) studies in case of stabilized nanofluid. Impact of variation of frequency and addition of harmonics was also analyzed to understand effect of degradation of power supply quality on dielectric properties of oil. It was observed that there is negligible effect of supply voltage frequency for all the samples, whereas a significant decrease was observed in CIV on addition of harmonics. Apart from visual changes, the results acquired from viscosity, turbidity, UV-vis analysis and fluorescence spectroscopy indicates that presence of nanoparticles act as an ageing barrier and helps enhance the lifetime of the insulation.

Apart from visual changes, the results acquired from viscosity, turbidity, UV-vis analysis and fluorescence spectroscopy indicates that presence of nanoparticles act as an ageing barrier and helps enhance the lifetime of the insulation.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"88 1","pages":"282-286"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81435866","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}
