Utilization of renewable energy resources is gaining momentum in several countries. Establishment of distributed renewable energy plants would cover the regional needs of the country besides sharing the power distribution with other parts of the country. For implementing this establishment, the country is proposed to be divided into several power regions named as cells or nodes and one or more renewable energy plants could be installed in each node. The power network connects all these power plants and maintains the distribution of power for the whole country. Pumping of external power might be needed to nodes facing deficiency in power. If power nodes generate excess power than meeting their demands then the additional power generated could be transported to the other nodes in the network. A financial analysis is made for a sample node and its resource units as to assess their financial involvement in initial investment and maintenance and the profits realizable in long run. This would present the information about the success of the establishment of distributed renewable energy plants in the power network.

Demand Response (DR) has gained importance in the recent years. The prime objective of DR is to reduce the maximum demand. There are various DR schemes. This study focuses on price based DR schemes in which consumer is motivated to change his load demand pattern by pricing based incentives. The paper presents an algorithm to solve the load scheduling problem under variable pricing scheme. To this end the paper formulates the load scheduling problem as a singe stage decision making problem and solves it using Pursuit Algorithm, which maintains an agreeable balance between exploration and exploitation. An algorithm to generate realistic loads is also presented. Simulation experiments were conducted considering different types of loads and pricing.

A lot of things determine the life expectancy of a transformer such as overheating due to triplen harmonics, unbalanced loading, vibro-acoustic noise and so on. For this reason, this paper presents the investigation carried out on the magnetostrictive sound of Bauchi, 30/40 MVA, 132/33 KV substation transformer. Readings were taken using standard audio recording instrument for various loading and voltage conditions in the mornings, afternoons and nights for six days and the offline assessment was carried out using digital spectrum analyzer. However, no access could be gained to the variation of certain important parameters, like changing of core dimensions, loosing or tightening of core and so on, for the substation transformer in-situ in the substation hence separate laboratory test transformers were used in the assessment of the effect of core damping pressure, construction looseness and transformer saturation on the vibro-acoustic noise. Conclusively, increasing the operation voltage of transformer tends to produce more magnetostriction effect while loosening core lamination increases the energy losses.

This paper presents the mathematical modeling of Compressed Air Energy Storage, (CAES) in obtaining mechanical power generated from expander. Mechanical power is injected to a generator to generate electricity that will stabilize 2MW active power fluctuated caused by intermittent behavior of wind speed. The control system in maintaining dc-link voltage at constant value and control system in supplying generated power from CAES is also discussed here. The goals in using CAES are to smooth out the fluctuated power and increased low power integrated into the grid. This system is analyzed using SimPowerSystem of MATLAB/simulink. Results show that the jCAES is able to not only mitigate generated power but it also can promise constant power generated to grid even at low wind speed.

Failure of vacuum metal clad switchgears often results in major load loss and long restoration time. Failure analysis is conducted with the aim to prevent future recurrence, thus an improved life of the equipment. This paper presents two failure cases of vacuum metal clad switchgears which had suffered from flashover. Both switchgears were connected to a local transformer and had exhibited similar post-fault damage characteristics. Evaluations techniques used to assist the analysis process include visual examination, photo documentation, tear down examination, electrical data analysis and computer simulation. The significant effect caused by the use of under sized cable is discussed. In the first case, a fault had occurred downstream of the switchgear. The cable had melted, causing significant damage inside the switchgear. From calculation, it was deduced that the minimum cable size needed to cater the fault current was 135 mm2. In this case, it was found that the existing cable was grossly under sized. For the second case, the minimum cable size calculated was 74 mm2. A computer simulation was carried out, in order to further verify the short circuit capacity and corresponding melting temperature of the 70 mm2 cable. From the simulation, it was found that the maximum permissible current before melting was 6.3 kA. The actual fault current of 8.8 kA had far exceeded this value. As a result of under sizing, both the cables could have melted and vapourised during fault current flow and subsequently caused explosion inside the switchgear.

An investigation of magnetizing current waveforms of single phase power transformer due to DC bias injection through simulation and experimental study is present in this paper. A method base on MATLAB simulation that is capable of predicting of magnetizing current without and with DC bias is used. The experimental study is done by the DC bias current injected simultaneously with AC source to primary winding of transformer and the secondary side is open circuit. The results show that the waveforms distorted when the DC bias exist. The pulsated waveforms are pushed to half cycle in which the bias current is in the same direction as magnetizing current (unsymmetrical pulsated) and even harmonics are significant. The simulated waveforms have good agreement with the measured one.

On Load Tap Changer (OLTC) failure occurs is due to the insulation degradation and contacts failure inside it. Other than that, contacts wear influences the OLTC performances. The worn contacts will cause hotspots in the OLTC tank and cause the insulating oil to degrade faster. As a result, this will lead to the damage of complete transformer unit. Thus, the research work that has been carried out applied the Dissolved Gas Analysis (DGA) via latest Duval Triangle method during the diagnosis of OLTC at the first stage to provide early indication of OLTC's breakdown. The Static Winding Resistance Test is then applied at the second stage to figure out any increase of contact resistances for all phases. The capability of Static Winding Resistance Test in order to provide any sign of bad contacts in fixed condition can be done by comparing two different conditions which are before and after maintenance.

Preventing voltage collapse occurrences in power systems are a challenging task worldwide. An adequate reactive power supply along with voltage limit violation may lead to blackout. The ability to sense such dynamic change and accurately determine voltage stability indications allows system control to take the necessary action to prevent such incidents. This paper presents efficient indices to calculate voltage stability analysis and predict system voltage collapse. Voltage stability margins can be calculated indicating how far the power system is from its severely loading condition. The proposed method was demonstrated on the 5-bus and IEEE 180-bus systems and compared with existing methods to show its validation and efficiency.

This paper presents the effect of supply voltage on partial discharge properties in solid dielectric. The study characterizes a pre-developed model which represents void in a solid dielectric. This model is used to investigate the interaction between discharges in such void in a solid dielectric when high AC voltage is applied to the system. Void and solid dielectric parts are represented as lumped capacitances, while the resistances of the test voltage source are taken into consideration. The simulation of partial discharge activity due to presence of a small cylindrical void inside the solid insulation material of high voltage power equipment is simulated using Electromagnetic Transients Program (EMTP). The waveforms of the voltage across the void and the voltage across the neighbouring parts of the solid dielectric have been traced by using EMTP. Simulation results indicated that the model is able to identify the correlation between input voltage with respect to peak partial discharge voltage and induced capacitance in the system.
