“…With a higher penetration of PV in the generation mix, significant grid stability issue may arise. For instance, as an intermittent energy source, the inconsistent power generated by solar PV technology can cause significant voltage fluctuation . The use of inverters in PV systems also introduces harmonics to the connected power grid, which can damage nearby sensitive equipment .…”

Summary Solar photovoltaic technology is intermittent in nature and employs power converters for grid‐interconnection, which can bring stability and power quality (PQ) issues to the power grid. Therefore, a set of testing guidelines is required to assure that solar plants comply with the grid and inverter requirements. As such, this article presents comprehensive testing guidelines for the interconnection of solar systems into Malaysian power grid, including inverter and PQ tests. The test points, conditions, parameters and acceptable limits for both tests are discussed in detail. This article also presents the results of a case study in which the testing guidelines were applied to examine the PQ of an actual grid‐connected solar photovoltaic plant in Malaysia and to assess the performance of the smart inverter used in the tested solar system. The testing outcomes, which were recorded by a PQ analyser, showed that the tested solar system was in compliance with all the requirements stipulated in the testing guidelines. The findings presented in this article will help relevant parties to understand these solar testing guidelines and serve to promote the wide deployment of solar technology towards a clean and sustainable future.

“…It features remarkable properties like accuracy and robustness. Sliding mode control method is a kind of varying structure control in which alteration of the dynamics of a nonlinear system is achieved by applying switching control and this switching is done at high frequency [18]- [22]. In state space current position is checked for each instant and switching is done to vary the system structure in state space from one continuous structure to another as per requirement.…”

<span>A sliding mode controller for a non-isolated DC/DC, bidirectional converter is presented and comparative study with PI controller is done along with ISE analysis, in order to do performance analysis. The proposed system can be utilized in many applications such as electrical vehicle, distributed power generation or small grids. Second theorem of Lyapunov is utilized and stability of the closed loop system is mathematically proven. The adopted control strategy achieves effective output voltage regulation and good dynamic stability. Rejection of disturbance is also an inherent characteristic of this technique. Furthermore, it is illustrated that the system can successfully follow changes of load demand and compensates sudden disturbances in operating condition. The design is evaluated and verified using Matlab/Simulink. Results of Matlab simulation are provided to show the feasibility of the proposed system and effectiveness of control method. Simulation results show that this technique can provide a considerable edge over control techniques which are presently available (applied) over this type of converter.</span>

“…To achieve maximum power at all times, the Maximum Power Point Tracking Technique (MPPT) is developed. Till now, the MPPT algorithms comprise the constant voltage tracking (CVT), voltage feedback, Perturb and Observe (P&O), power feedback, incremental conductance (INC) method, Hill Climbing, Artificial Neural Network (ANN), Fuzzy Logic, and so on [1][2][3][4][5][6]. The simplest approach is the voltage feedback, where the output voltage at the maximum power point is essentially recognized in advance of the tracking operation.…”

Maximum Power Point Tracking (MPPT) technique is used to extract maximum power from the photovoltaic system. This paper involves working on an enhanced Particle Swarm Optimization (PSO) based MPPT method for the photovoltaic (PV) system integrated through Z-Source inverter. The main benefit of the proposed method is the diminishing of the steady-state oscillation when the maximum power point (MPP) is located. Additionally, during an extreme environmental condition, such as partial shading and large fluctuations of irradiance and temperature, the proposed method has the capability to track the MPP. This algorithm is implemented in dspace 1104 controller. MATLAB simulations are carried out under varying irradiance and temperature conditions to evaluate its effectiveness. Its performance is compared with a conventional method like Perturb and observe (P&O) method.
