Voltage stability improvement using line voltage stability index based on optimal power flow (OPF) in power systems is presented in this work. Line voltage stability index (LVSI) traditionally adopted to identify the most critical line in the system where its value is in the range of 0 (no load) and 1 (voltage collapse) has been applied as part of the constraints to prevent the system from the voltage collapse. LVSI has also been adopted as the objective function to enhance system stability. The OPF problems have been solved by using salp swarm optimization (SSO). The voltage stability improvement has been investigated in the IEEE 30-bus system. Two conditions consisting of stressed load condition where the load demand is raised and line outage contingency condition where the most critical line is considered for outage have been considered to evaluate the performance of the voltage stability improvement. The simulation results of considering LVSI as part of the constraints and objective function are compared with the base case where fuel cost is the objective function. The results express that the system stability can be significantly improved.

The objective of this research work is to search for an appropriate generation schedule satisfying system constraints and unit operation constraints with effective spinning reserve. The work was presented in two papers, which are part I and part II. This part I paper deploys the problem formulation of generation scheduling with virtual load constraints to ensure that spinning reserve could be used effectively without line congestion problem by expecting higher load demand in next few minutes. The part II paper is the simulation result and discussion of the proposed method. In the proposed method, the hybrid mixed integer programming process includes mixed-integer linear programming and quadratic programming (MILP-QP) is used to find the feasible solutions with total cost minimization while satisfying all important constraints. MILP is used to find generation schedule whereas QP is used to perform economic dispatch.

This paper presents an implementation of a zero-voltage and zero-derivative-switching (ZVDS) Class-DE bridge rectifier with an LCC series-parallel matching network to improve an output voltage regulation from light load to heavy load of a high-step up zero-voltage switching (ZVS) push-pull resonant converter. The LCC series-parallel matching network is placed between the secondary side of the transformer and the ZVDS Class-DE bridge rectifier. The secondary leakage inductance and the junction capacitance of the rectifier diodes can be used as part of the resonant inductor and the resonant capacitor, respectively. Additionally, the proposed push-pull resonant converter has a soft-switching characteristic that reduces switching losses and switching noise. A prototype for a 200 W front-end DC/DC converter for distributed power generation based on 24 VDC battery as an energy storage and 400 VDC output voltage has been developed and tested to evaluate the performance of the proposed approach.

This paper proposes a control algorithm for photovoltaic hybrid power system with a supercapacitor storage device and an energy management of AC distributed system supplied by a hybrid source that uses supercapacitor (SC) as secondary source, in association with a photovoltaic (PV) as the main source. In this power plant, the PV (1.5 kW) is used as the main source to supply power to the load and charge the SC, and the SC (41 F, 192 V) functions as an secondary power source to regulate the AC output voltage and control system performance when electrical loads demand high energy in a short time. The experimental results presented that the control algorithm of the hybrid power system can work efficiently.

The Energy Conservation Promotion Act 1992 and Energy Conservation Promotion Act 2007 (Version 2) promote the country to produce and use energies effectively and economically. In addition, they encourage people to make use of more alternative energies. In section 7, it is mentioned that energy conservation in factories can be done in one of the following ways: (5) improving electricity usage by correcting power factor, reducing peak electricity demand of the system, using electrical equipment which is suitable for the load, (6) the use of high-efficiency machinery or equipment including the operational system which controls them, the use of materials which help to conserve energies. In accordance with the Energy Conservation Promotion Act 1992 manual (amended in 2007), a building needs to be constructed with the standards, criteria and methods prescribed in the Ministerial Regulations. In Rajasudasambhava 60 Building, the sizes of each classroom and office are different, therefore the control system of electricity usage in each room is different, the number of lamps in each room is different, and the electrical energy which is consumed by the lamps in each room is different. In the present, energy conservation technology is diverse and it is easy to choose the right technology and electrical equipment which match the needs of consumers. Moreover, the use of electricity in the system becomes less and more economical. The researchers have created this project to study efficiency in each room. From the study, it is found that the electricity usage of the building is increasing every year. In 2019, the electricity usage increases from the year 2018 by 10.09% and the electricity usage in 2018 increases from 2017 by 1.49%. The difference of percentage of each year is quite obvious. Before the project had been undergone, most of the lamps are on the surface because the ceiling of the building has no cover, showing the pipes and conduits for the sake of maintenance. The lamps have the reflector which is made of shiny aluminium. Most of the lamp covers are acrylic and the power is 14 watts and 28 watts. The ballast is a low-loss type. The power consumption is 6 watts. Each lamp is turned on 301 days per year and 6 hours per day, approximately from 9.00-16.00 hrs. The average illumination is 1260 lux. The calculated illumination power is 59.6 watts per square meter in average. The process of this project is as followed: 1) using Dialux program to simulate the lighting system of 10 rooms. 2) experimenting by reducing energy consumption by two methods which are using natural light and changing electric lamps. The result is, when using natural light, the use of electricity is reduced by 11.74% and when changing electric lamps, the reduction is 39.12%. In conclusion, the lighting requirement of the building should be 1) to use more natural light. 2) when the lamp is damaged, the light bulb which is brighter than the original lamp should be replaced, so that we

An increase in interconnection of power systems may lead to poor damping oscillation. This paper studies the oscillation damping performance of the Power System Stabilizer (PSS) and Power Oscillation Damper which are located on a photovoltaic plant (PV-POD). A computer simulation of a power system with PSS and PV-POD is conducted in Matlab/Simscape Power System. The study consists of five scenarios with different operating conditions. To compare the damping performance, the results from the Eigen analysis and time domain analysis from the computer simulation are used to analyze the damping quality. The results show that the oscillation damping obtained from the system with POD is better than that from the system with PSS. However, when the operating condition of the system is changed, the oscillation damping of the system with PSS is more consistent than that of the system with POD.

Regarding the increase in electrical power demands, distributed generations (DGs) from renewable energy resources are becoming essential for electrical generation systems. However, there are no specific requirements for DGs allocation in a distribution network. The improper installation of the DGs can cause crucial issues to electric utilities and customers, such as the increase in energy losses and the improper voltage drop in the networks. In this paper, the optimal distribution network reconfiguration implemented with a tie line and a capacitor is proposed to enhance system efficiency and mitigate the impacts of the improper DGs installation. The optimal allocation of the tie line and the capacitor is determined using an improved particle swarm optimization (I-PSO) technique to minimize the energy losses and improve the voltage profile. The proposed network reconfiguration approach is implemented into a practical distribution network with a high installed capacity of the biomass DG unit from Kamphaeng Phet province, Thailand. The simulation test results show that the proposed approach can significantly reduce not only the energy losses but also the voltage drop in the network.
