This paper presents an improved state-of-charge feedback (SOC-FB) control scheme for battery energy storage (BES) for used in hourly dispatch the output of hybrid photovoltaic (PV) with battery energy storage (BES) system. Heuristic optimisation approaches employing the genetic algorithm, gravitational search algorithm and particle swarm optimisation are used in obtaining the optimal control parameters for the SOC-FB controller in tracking the hourly dispatched set-point (PSET) curve of the PV/BES system. The studied multi-parameter optimization problem also considers the evaluation of the optimal size of the BES. The performance of the heuristic optimization techniques are validated by comparing the results obtained from Matlab simulation with the results from previous works. In addition, the optimal controller with the proposed BES size is further validated through simulation using an actual PV system output data.

With the advent of smart grids it is becoming possible to reduce the peak-to-average ratio (PAR) in electrical demand by transitioning household appliances to off-peak hours. As electric vehicles (EV) become more numerous it will be increasingly important to shift the power consumption of EV from peak times since EV have the potential to consume as much as an average home and so increase the PAR considerably. However, integrated correctly into the electrical grid, EV represent a huge opportunity, as they can assume the role of a dispatchable energy resource that helps meet load demand from homes during peak times. A mathematical optimization based model consisting of household appliances and a sizable number of EV vehicles connected to the grid is developed. A mixed integer linear programming (MILP) based optimization technique is proposed to minimize the peak hourly load by scheduling the optimal power and operation time. The model ensures battery charging losses and degradation are minimized. It is shown that ILP is an extremely robust consumption scheduling method as the overall power load is balanced for various penetration levels.

The decomposition and coordination calculation among multiple control centers can solve the contradiction that power systems have been interconnected while they are managed and controlled hierarchically. But distributed calculation is a complex process which involves problems about multi-regions, multi-users and multi-applications, therefore the distributed parallel calculation management mode is needed for realization. Considering from the practical point of view, this paper designs the distributed parallel calculation management mode with the decomposition-coordination mechanism, master-slave mechanism and parallel calculation mechanism. It marks the objects with time, space and application dimensional coordinates to realized the isolation and stratification of data. Therefore, it can solve the problems that applies the decomposition and coordination calculation to the reality. In addition, this paper uses distributed management mechanisms like registering, activating and calculating to manage the status of subsystems, and realizes it with hierarchical objects, forms the sequence of execution.

The majority of modern loads are based on power electronic devices, resulting in harmonic current emission. In consequence, increasing harmonic voltage levels are observed in distribution grids. Shunt active power filters (SAPF) can decrease the harmonic voltage distortion with a voltage-based harmonic compensation scheme. This paper presents a method for voltage-based selective harmonic compensation (SHC). Multiple complex coefficient filter (MCCF) state estimation is utilized for harmonic extraction. Stationary frame generalized integrators (SGI) provide control of the selected harmonic compensation. As the voltage-based SHC is implemented in stationary reference frame, computational efforts are reduced compared to synchronous reference framed SHC methods. In addition, the MCCF state estimator determines grid fundamental for robust grid synchronization in presence of imbalance and harmonic voltages, further decreasing computation requirements in the overall SAPF control. Simulation results validate the effectiveness of the proposed method.

This paper proposes Model Predictive Control (MPC) for single-phase grid connected inverter for PV applications. The proposed single-phase inverter is a five-switch inverter. The inverter is controlled to inject sinusoidal current into the grid. MPC provides control of the amplitude and frequency of the injected current. Five-switch inverter consists of an h-bridge inverter and extra switch is added. The added switch enables reduction the switching losses and voltage stresses of the h-bridge inverter switches. The proposed system has some inherent features such as high gain, reduced switching losses and reduced switches voltage stresses. Detailed analysis of the principle of operation and simulation results will be discussed in details.

This paper proposed a 43-level 3-phase 33 kV modular multilevel cascaded (MMC) converter for direct grid integration of renewable generation systems. A high-frequency magnetic-link is considered to generate isolated and balanced multiple dc sources for all of the H-bridge inverters of the MMC converter. The proposed converter is designed and analyzed taking into account the specified system performance, control complexity, cost and market availability of the semiconductors. The simulation results demonstrate the excellent feature of the proposed medium-voltage converter. It is expected that the proposed new technology will have great potential for future renewable power plants and smart grid applications.

Home automation systems represent the front-end of smart grids, where the energy monitoring and control operations are enabled through smart devices installed in households and residential buildings. There are many home automation technologies available in the market, and the users are left to select their choice of best technology. Proper guidelines to their selection currently remain low. Therefore, in this paper, a comparison of popular home automation technologies is presented from user perspective to fill this void in the research literature, and to empower the users with more details based on the current home automation market. X10, Z-Wave, ZigBee, INSTEON, and EnOcean are the home automation technologies compared in this paper. Two indices are developed as the outcome of this paper to represent the performance and affordability of these technologies, as a guideline to the potential users. We find these technologies fit out a tradeoff of higher performance and price (Z-Wave) down to lower performance and price (X10). With this understanding, appropriate choices can be made.

Electrical vehicles (EVs) have appreciated much attention with the increasing pressure on the environment and energy supply. Considering that user gets revenue by arbitrage, we propose an optimal charge control model for plug-in Electric Vehicles to minimize user charge cost in an open and perfect electricity market. Based on the model, combining the analysis of the charge power demand, we calculate the user revenue expectancy of uncertain trips through the Monte Carlo Simulation and analyze the factors influencing the revenue. The results show that the arbitrage can raise user revenue significantly. In addition, price fluctuation has great effect on user revenue and price signals are able to adjust user charge/discharge scheme effectively.

The estimation of Maximum Power Point (MPP) of photovoltaic (PV) array is essential for integration of solar power to microgrid. This paper presents the estimation of Maximum Power Point of a solar photovoltaic array under different environmental conditions (i.e. different temperature and solar irradiation) using Levenberg Marquardt method. The estimation is done using the single diode based model parameters of photovoltaic (PV) module. The photovoltaic (PV) module parameters are estimated from the data sheet values given by manufacturer. The estimated Maximum Power Point (MPP) values of the PV array under different environmental condition are presented in the simulated current-voltage and power-voltage characteristics. It is demonstrated that the estimated MPP values of the PV array are nearly equal to simulated MPP values.
