    In recent years, the proliferation of nonlinear electronic loads injected harmonics into the distribution network and polluted the supply network with power quality problems, Compensating type of custom power devices (CPD) is the possible solution to solve the power quality issues at the Point of Common Coupling (PCC) such as harmonic elimination to comply with the IEEE Standard 519-2014. Distribution Static Compensator (DSTATCOM) is a shunt connected CPD which found to be an effective solution to mitigate the current related power quality problems especially harmonic currents due to its fast and smooth response during load perturbation. The effectiveness of DSTATCOM depends on its control algorithms to generate the switching signals for the Voltage Source Inverter (VSI) and injecting the compensating currents at the PCC. This research work presents new topology of PV based DSTATCOM with three new main control algorithms proposed for it which are Voltage Reference Configuration (VRC) control algorithm, Back Propagation Neural Network (BPNN) and Radial Basic Function Neural Network (RBFNN) for power quality improvement in term of harmonic elimination under nonlinear loads. These control algorithms are required to extract the reference line currents from the distorted load currents in order to inject the compensating currents with current error at the point of common coupling (PCC) to match the line currents as close as possible with the reference line currents. Thus, the proposed DSTATCOM will force the PCC line currents to be sinusoidal, low current harmonic according to IEEE Standard 519-2014 and in-phase with the line voltage. The performance of DSTATCOM is validated using MATLAB software with its Simulink and Power System Block set (PSB) toolboxes. The optimum design of PV array with DC-DC boost converter is evaluated its viability in term of technical and economic aspects for continuous renewable supply and reduce the cost of electricity (COE) with Homer Pro software. Prior to hardware implemented to verify its effectiveness. Then, a prototype of DSTATCOM is developed using an Altera FPGA Cyclone IV EP4CE115F29C7N FPGA board and its performance is studied under steady-state and dynamic conditions. The performance of the DSTATCOM with the proposed control algorithm is found to be satisfactory under nonlinear load condition for harmonic elimination at the PCC in the three-phase three-wire low voltage distribution system.

    Rapid global economic growth and growing population have tremendously led to the increasing demand for energy needs in commercial and residential buildings. The main energy resources for electrical energy generation in Malaysia are fossil fuels. The increase in electricity demands causes simultaneous proportional growth in fossil fuel consumption, thereby leads to higher greenhouse gas emissions. Buildings have emerged as the most voracious electrical energy consumer which contributes over one-third of global energy consumption. Furthermore, lightings and air-conditioning systems have the most significant impacts on the total electricity usage of buildings in Malaysia. Thus, energy efficiency efforts targeting both loads will significantly reduce total energy consumption in the buildings. This paper aimed at reviewing energy efficiency efforts at the commercial buildings and comparison between simple strategy and SMART Building by using Building Energy Management System (BEMS). Many aspects of energy efficiency efforts will be considered such as energy consumption, occupant comfort, and system cost. Furthermore, suggestions for improving energy efficiency in the commercial building using the best strategy to reduce energy consumption by using a lighting control system will be discussed.
