Smart building technology with multi occupants with shared spaces such shopping mall, airport lunges, corporate house, hotels and school colleges etc. are often occupied by multiple occupants that typically have different temperature requirements. Attaining a preferable temperature based on the occupants in a multi zone area is a challenging problem. Also in a multi zone space if temperature is controlled at different set point then it also increases the energy savings in the overall system. Using the concept of consensus we propose a distributed multiparty control strategy to maintain the different temperature set point in different zone. The space under concern are partitioned into different zones (or parties), among which each zone is describes by a temperature model, is consider an agent. The proposed method within the same party are synchronise with each other, but agents or zones from different parties have different target trajectories. One typical treatment on this is to use complex numbers to describe relationship among all target trajectories in different parties, which nevertheless significantly reduces its applicability to problems with complex target formations. In this paper we propose a matrix-based technique to capture information interactions among agents of different parties, making it suitable for tackling consensus problems for a larger variety of formations. Simulation studies demonstrate the effectiveness of the proposed approach.

Photovoltaic (PV) sources are inherently nonlinear power devices and maximum power derivation depends on Maximum Power Point Tracking (MPPT) algorithms. The algorithms require testing in real time situation using PV source which will be troublesome due to higher dependency on environmental factors and larger space requirements for higher power rating. The increased and faster testing lead to develop a PV emulator with desired performance and lower price compare to the commercially available PV emulators. In this paper, design of a digitally controlled PV emulator with varying resistive load is proposed to replicate the behaviour of real PV sources. The power stage of the PV emulator is realized using dc-dc buck converter topology and the controller stage uses an algorithm-in-loop Newton-Raphson (NR) method. Finally, the PV emulator is tested with MPPT controlled dc-dc boost converter for battery charging. The design of the power and control stages of the PV emulator has been compared with the real PV source and it is observed that the obtained V-I characteristic is in good agreement. Moreover, an analysis is presented for different switching frequencies of the boost converter connected as load to the fixed switching frequency buck converter, i.e., PV emulator. Further, a schematic hardware circuit diagram has been given to realize the proposed digitally controlled PV emulator.

State of Health (SoH) estimation is one of the most important functions of the Battery Management System as it ensures safe and reliable operation of Lithium-Ion battery. SoH estimation is done by developing a regression model between SoH and Health parameter, by studying the charging dataset of the battery throughout it’s working life (upto 60 % SoH). The health parameter is calculated as the charging time between two selected voltage ranges instead of taking the entire voltage range. The selection of the voltage range for SoH prediction is done based on the goodness of fit of the regression model. The training dataset consists of health parameter evaluated at regular intervals of SoH. The regression line is tested with a wide range of test data and the accuracy is found to be over 99%.

Recent advances in power electronics have led to increased use of electricity from renewable energy systems, such as photovoltaic (PV) as well as wind energy systems. Developments in power semiconductor technology, i.e. a wide band gap, have increased the conversion efficiency of power electronics to more than 98%, however the dependability with power electronics is becoming a major concern. Junction Temperature is the primary parameter that affects this same reliability of the IGBT. Mission profile (Solar Irradiance & Ambient Temperature) variation throughout junction temperature tends to lead to mechanical failure (Bond wire lift off, solder fatigue etc.). Therefore, in order to assess reliability, the junction temperature needs to be estimated. But the junction temperature cannot be calculated directly, it requires an indirect method of estimation and validation. The 3 kW grid connected to the PV Inverter is however discussed in this paper. PV Inverter consists of four IGW30N60H3 IGBTs from the Infmeon manufacturer. Annual mission profile data is logged in Hyderabad, India. Foster electro thermal modeling (ETM) is held out for junction temperature evaluation. Validation for the estimated junction temperature is required as estimated by indirect method. Finally, the estimated junction temperature is validated by correlation with annual solar irradiance, ambient temperature and case temperature.

Large-scale energy storage applications require multiple lithium-ion battery packs operating in parallel. Such applications comprise of renewable energy storage systems, battery packs for large-scale automobiles such as electric trucks, tanks, armoured vehicles, diesel-electric submarines, etc. The current technology to enable parallel operation of multiple battery packs is quite hardware intensive. It requires a separate pack management system operating as a master and battery management systems in each of the battery packs configured as slaves. This significantly affects the scalability of such systems as the number of battery packs that can be connected in parallel is completely dependent on the capacity of the master. This paper presents an alternative approach through a decentralized pack management system. The proposed approach does not require the master-slave configuration of battery packs and does not require any centralised hardware to manage the battery packs. Instead, this methodology enables the individual battery packs to communicate with each other independently thereby enabling decentralised pack management. Thus, there is no theoretical limit to the number of packs that can be operated in parallel and this allows the system to be capable of scaling up to meet virtually any size, small, medium or large.

Extensive Converter-Interfaced Renewable Energy Power Plants (CIREPP) are of focused on integration with the grid. Fault Ride-Through (FRT) scheme followed by grid code is the capability of generation plant to stay connected in voltage dip even fault duration for some period to prevent the unwanted detach of Renewable Energy Plant (REP) from the power system. This scheme causes the phase angle difference between source end current and load end current. And modulates the voltage and current in fault duration, which can cause the calculated impedance with local data available at the relay is out of the trip boundary of the Distance Relay, which leads malfunction of the relay. The proposed scheme calculates the angle, which is a function of fault current with the help of realfault impedance of the REP and calculates the impedance from fault inception point to relay location point. The challenges brought by the FRT scheme studied and the proposed method verified on the IEEE-39 bus system integrated with a typical Solar power plant in PSCAD/EMTDC.

In the present scenario due to the advancement of technology energy consumption per capita has increased a lot. But the natural resources like fossil fuel are depleting day by day. To enhance the use of renewable energy in the present situation the development of converter circuit is most essential. This paper proposed a newly modified multi-input interleaved DC-DC boost converter. This proposed topology interfaces three unidirectional input power sources in a combined structure. This converter is attractive for alternative energy sources such as photovoltaic sources (PV), fuel cells, and batteries. This paper aims to design a high-performance multi-input boost converter. The proposed topology uses five switches that are separately controlled with five different duty ratios. Computed duty ratios are applied at different modes of operation and hence the switch realization of the new converter is obtained. The proposed topology has been realized through simulation using the MATLAB Simulink. The outputs of the simulated circuit confirm the feasibility of real-time implementation.

Modularity, low losses, scalability as well as low filtering requirements make the Modular Multilevel Converter (MMC) a best solution besides HVDC implementations. But still the key concern associated with the implementation has been the voltage balancing of capacitors of about their sub - modules (SMs). Even though the MMC does have an attractive configuration with such a variety of notable features, a sophisticated control method is designed for desirable process. Pulse-width modulation (PWM) control strategy of various combinations, such as phase and level-shifted carriers, has been the most popular MMC deployment. However, the difficult positioning of a significant number of SMs as well as a high switching frequency seems to be constraints of PWM techniques. Even so, Nearest Level Control (NLC) provides a lower switching frequency and easier implementation. Due to its flexibility as well as easy implementation, NLC has become the most famous having to balance methodology for MMC SMs. The research article provides an insight that the use of NLC for 5 levels of MMC, where neither individual sub-module status has been required at the gate pulse generation stage. SM Identification is done upon sorting of sub-modules and the logic of a gate voltage level switching could be assessed. Throughout this article the MATLAB simulation has been conducted out on 5 levels of MMC with simplified NLC and the control strategy of PWM. Just on basis of the results obtained, a comparative evaluation between two techniques was carried out.
