 The research was conducted at the Bohol Island State University Main Campus. It aims to assess the status of the electrical power system of the university as well as determine the perceptions of the electrical experts on the satisfaction rating of the school’s electrical system. It was found out that the overall rating of the electrical system of BISU Main Campus is “fair”. This means that there are several aspects that need improvement such as the implementation of a maintenance program and the hiring of maintenance personnel. The researchers recommend that the personnel should not be the instructors themselves but designated electrical technologists must be hired. Furthermore, there should be a periodic inspection so that defects may be detected and given remedies the earliest time possible to avoid accidents. There should also be fund allotment that should be imposed for the maintenance and personnel. Furthermore, the university must purchase more electrical supplies, tools and equipment solely for electrical maintenance. There must also be a separate maintenance shop for maintenance purpose only. An alternative electrical power source should be employed by the university such as the solar power. Because of the very high and expensive electrical energy consumption, there is a need to use a more efficient alternative source and that is the solar power. Keywords - electrical power system, electrical energy consumption

The electrical power system is considered as the most complex man-made systems mainly due to their wide geographical coverage. Electrical energy industries contributes environmental pollution which rise questions concern environmental protection and methods of eliminating or reducing pollution from power plants either by design or by operational strategies. Electric power plants are mainly aimed to operate al low fuel cost strategies .In this paper a Multi –Objective Economic Emission Load Dispatch problem is solved to minimize the emission of nitrogen oxides (NOx) , oxides of other fuels that release during generation of electricity and fuel cost considering both Thermal generators and Wind turbines. A large number of iterations and oscillation are those of the major concern in solving the economic load dispatch problem by using the BFO(bacterial foraging optimization) method. By applying BFO method the economic dispatch problem is optimized to minimize the total generation cost of a power system while satisfying various equality and inequality constraints. The effect of Wind power on overall emission is also investigated here using Quadratic programming by wolf’s method. This method has better convergence characteristic. Wolf’s method is an extended simplex procedure which can be applied to Quadratic programming problems in which all the problem variables are non-negative.

Utilization of renewable energy for the reduction of fuel consumption and green house gas (GHG) emissions in the shipping industry has been increased rapidly in the recent years. Wind energy is a clean renewable energy with no pollution which is abundantly available at sea. This paper proposes two different possible configurations of connecting wind power energy into the ship’s main grid bus system . Wind electrical energy output has been connected to ship’s main ac bus system in one configuration and it is connected to ship’s main dc bus system. Even though Wind assisted ship propulsion (WASP) had been started already in the last decades in the form of wing sails, kites, Flettener rotor etc which could assist auxiliary propulsion of the ships, the application of wind power generator on the ship is not often applied. Therefore this paper has a relevant significance in applying wind electrical energy for the marine electrical power system needs. This paper also reveals the benefits and challenges in the area of onboard wind generation and opens future research possibilities in integrating wind energy into marine industry.

The ever increasing global demand on the electrical energy has lead to the integration of Distributed Generators (DGs) onto the distribution power systems networks to supplement on the deficiencies on the electrical energy generation capacities. The high penetration levels of DGs on the electrical distribution networks experienced over the past decade calls for the grid operators to periodically and critically asses the impacts brought by the DGs on the distribution network operations. The assessment on the impacts brought by the DGs on the distribution network operations is done by simulating the dynamic response of the network to major disturbances occurring on the network like the faults once the DGs have been connected into it. Connection of Wind Turbine Generators (WTGs) into a conventional electrical energy distribution network has great impacts on the short circuit current levels experienced during a fault and also on the protective devices used in protecting the distribution network equipment namely; the transformers, the overhead distribution lines, the underground cables and the line compensators and the shunt capacitors commonly used/found on the relatively long rural distribution feeders. The main factors which contribute to the impacts brought by the WTGs integration onto a conventional distribution network are: The location of interconnecting the WTG/s into the distribution feeder; The size/s of the WTG/s in terms of their electrical wattage penetrating the distribution network; And the type of the WTG interfacing technology used labeled/classified as, Type I, Type II, Type III and Type IV WTGs. Even though transformers are the simplest and the most reliable devices in an electrical power system, transformer failures can occur due to internal or external conditions that make the transformer incapable of performing its proper functions. Appropriate transformer protection should be used with the objectives of protecting the electrical power system in case of a transformer failure and also to protect the transformer itself from the power system disturbances like the faults. This paper was to investigate the effects of integrating WTGs on a distribution transformer Fuse-Fuse conventional protection coordination scheme. The radial distribution feeder studied was the IEEE 13 node radial test feeder and it was simulated using the Electrical Transient Analysis Program (ETAP) software for distribution transformer Fuse-Fuse protection coordination analysis. The IEEE 13 Node radial test feeder In-line transformer studied is a three-phase  step down transformer having a star solidly grounded primary winding supplied at  and a star solidly grounded secondary winding feeding power at a voltage of . The increase on the short circuit currents at the In-line transformer nodes due to the WTG integration continuously reduces the time coordination margins between the upstream fuse F633 and the downstream fuse F634 used to protect the transformer.

Desalination Plants

This article deals with the desalination of seawater and brackish water, which can deal with the problem of water scarcity that threatens certain countries in the world; it is now possible to meet the demand for drinking water.  Currently,  among  the  various  desalination  processes,  the  reverse  osmosis  technique  is  the  most  used. Electrical energy consumption is the most attractive factor in the cost of operating seawater by reverse osmosis in desalination plants.  Desalination  of  water by  solar  energy  can be  considered  as a  very  important  drinking  water alternative.  For  determining  the  electrical  energy  consumption  of  a  single  reverse  osmosis  module,  we  used  the  System  Advisor  Model  (SAM)  to  determine  the  technical  characteristics  and  costs  of  a  parabolic  cylindrical installation and Reverse Osmosis System Analysis (ROSA) to obtain the electrical power of a single reverse osmosis module. The electrical power of a single module is 4101 KW; this is consistent with the manufacturer's data that this power must be between 3900 kW and 4300 KW. Thus, the energy consumption of the system is 4.92 KWh/m3.Thermal power produced by the solar cylindro-parabolic field during the month of May has the maximum that is 208MWth, and the minimum value during the month of April, which equals 6 MWth. Electrical power produced by the plant varied between 47MWe, and 23.8MWe. The maximum energy was generated during the month of July (1900 MWh) with the maximum energy stored (118 MWh).

The amount and the power of the electrical appliances on cars are increasing, and the fuel consumption produced by the electrical system is getting larger. To design an automotive electrical power system with higher efficiency is a very practical requirement. In this paper, we proposed an automotive intelligent alternator control system. In this system, we divided the battery states to different partitions by state of charge, and designed an intelligent alternator control system to work in different mode according to the battery partition and the vehicle state. With this system we can realize the braking energy regeneration for traditional cars and reduced the fuel consumption. We carried out the experiment with a car, and the results indicated that with this system, the fuel consumption can be reduced by about 2-3%.
