The aim of this paper is to propose an equality-constrained weighted least squares (WLS) algorithm for state estimation (SE) in electric power transmission systems including voltage source converter (VSC) based high voltage direct current (HVDC) links. The associated measurement model incorporates both AC and DC measurements. For the AC network, phasor measurement units (PMUs) provide voltage and current phasor measurements. DC measurements obtained from the DC lines are assumed to be sampled at the same rate as AC measurements. Then, by applying voltage and current phasors, linear AC and DC measurement equations are formulated in rectangular coordinates. Zero current injections and AC/DC coupling equations are considered as equality constraints. The applicability of the proposed approach is demonstrated by simulations on a 6-bus hybrid AC/DC network.

Reliable protection of the inverter-dominated microgrid is a technical challenge considering the peculiar behavior of the power electronics converters interfacing distributed energy resources with the grid. Traditional protection strategies fail to reliably detect the direction and type of faults in such microgrids. This paper introduces a non-pilot protection strategy using artificial neural networks. The proposed method is fast, secure, and robust against the microgrid mode of operation and parameters. Comprehensive simulation studies are conducted in PSCAD/EMTDC software to investigate the performance of the proposed protection strategy under different fault scenarios. The results indicate that the proposed protection strategy achieves 100% accuracy in fault direction detection and fault type classification.

Standalone renewable sources such as PV (Photovoltaic) and FC (Fuel cells) are often employed as input sources to supply high voltage DC buses of microgrids. Conventional DC-DC converter used as interlinking device would require a high duty ratio operation to meet the desired bus voltage which is usually perilous for the device health resulting in many detrimental effects such as diodes reverse recovery issues, unwanted transient response, losses and reduction in efficiency. To deal with such issues and for many other industrial applications, a two offspring family of Switched-inductor-capacitor (SLC) based converters have been discussed in this article. The proposed converter is realized without using any transformer, coupled-inductor, or cascaded and interleaved structures. Only two active switches with low voltage stress (half the output) are used to attain a sufficiently high voltage gain. Apart from the voltage gain, a critical inference is made after analyzing the reconfigured structure of an SLC network that a slight variation in the architecture delivers such a high gain compared to the counterpart design. The proposed converters have been analyzed theoretically in CCM and DCM, and then verified through the simulation results.

Inverters have many application areas including the variable frequency drives applications of the motor industry. Three-phase inverters based on the three-phase system that we are using are becoming more common. The implementation of the space vector PWM (SVPWM) modulation technique in three-phase inverters is more advantageous than other modulation techniques due to the lower harmonic content and higher DC bus utilization it provides. A delay time, also called the dead-time, is added to the rising edge of the PWM signals for triggering the gates of the switches to avoid shoot-through faults in the inverters. Although it has a protection advantage, it has some disadvantages such as output voltage drop, phase shift, zero current clamping and increase in total harmonic distortion (THD) of the output current. In this study, these effects of dead-time are compensated by employing the simple yet effective feedforward method using the SVPWM technique. Moreover, the relationship between the effects of the dead-time and switching frequency is investigated. The results exhibit that the THD of the current is optimized when the switching frequency is controlled rather than kept constant.

Air Quality Index data is observed across the country and seems not suitable for human kind. India is a country where a lot of potential and several plans are existing for Solar Photovoltaic (PV) based electricity generation. Such kind of generation is not only saves the transmission losses but mitigates the green house gases (GHG) emission in atmosphere in comparison to conventional generation. The investors are showing interest in these projects. In this paper an analysis is conducted for 50kWp Solar PV system to compare the actual GHG mitigation with reference to diesel generation. It is found that actual saving in CO2 emission is 0.211 US ton /year, SO2 emission is 0.0004 US ton /year and NOx emission is 0.0042 US ton /year. Although the system is not too large in rating but as compared to diesel it is mitigating 78.4% CO2, 80 % SO2 and 97.67 % NOx.

Solar-based systems represent the focal interest field for most of the newest studies of renewable energy. Solar heating and cooling systems convert thermal energy coming from the sun into electricity or heat to provide residential, commercial, and industrial areas with hot water, or to retain a specific required temperature. These technologies replace the classical fossil energy sources that are characterized by their damaging environmental impacts as well as their expensive costs. In this paper, we look at the ambitious solar projects that are already established or will be constructed in different countries of the ME and Turkey. Then, we discuss in brief most of the available technologies that rely on solar-based approaches for heating and cooling purposes. To overcome some challenges that may affect the performance of solar plants like cloudy or night environments, smart management techniques for interconnected units, or the cross-border power units of neighbored countries, are presented here and clarified by a case study. Finally, we conclude with a summary describing the most important features of our paper.

Smart energy management systems have shown lately efficient solutions to optimize the energy consumption, maximize the energy productions, predict the demand response, and grid self-diagnosis. These systems give insights on energy behaviour within the electrical power grid, where the consumers and producers can have real-time key performance indicators related to the energy that help them to take decisions in order to optimize their consumption. The management of loads and sources is a critical component of the mentioned systems especially when it comes to decentralized energy production within the grid, which create a huge energy market, where prosumers can buy and sell green energy interfacing with a certified agency that approve these transactions. The goal of this paper is to de-sign a blockchain base energy management system which enable a peer-to-peer energy market, the key element of this design is the power meters and their inter-actions with the electrical grid not only as measurement devices but also as digital wallet, that enable the prosumers to sell and buy energy. This concept integrates all blockchain components including cybersecurity, bidding techniques and welfare optimization. A simulation of these optimization techniques, hashing algorithms and their interactions with the smart meters to generate smart contracts and to increase security according to the blockchain concept were proposed.

Since some grounding transformers seem to be damaged due to the failure of the medium voltage cables in Turkey’s 1st region, it is necessary to investigate the system behavior, thoroughly. The main substation is modeled in detail, as well as the high voltage and medium voltage equipment connected to this. The Wye-delta transformer is grounded by a Zig-Zag transformer on the delta side. However, records indicate that the grounding Zig-Zag transformer was damaged by high fault currents on the medium voltage side. An appropriate and feasible solution is proposed by simulating and analyzing the possible scenarios. PSCAD software is used to simulate the event and examine the proposed solution. The final step of the analysis is to validate the results related to fault currents using the real-time simulation tool, RTDS through RSCAD software.

Due to the growing importance of demand response program (DRP) in demand side management in power systems as well as increasing employment of combined heat and power (CHP) units, the issue of energy management of large consumers equipped with CHP units in the presence of a DRP based on the day-ahead electricity price has been studied in this paper. To solve the considered non-convex and non-linear energy management problem, particle swarm optimization (PSO) algorithm has been used. Also, given the importance of the effect of uncertainties on the planning and operation of units in the energy management, the unscented transformation (UT) method is used for modeling uncertainties related to electricity prices and the amount of electric and thermal loads. In the applied DRP, the consumers can shift a percentage of their load from higher-price hours to lower-price hours to reduce operating costs. No load-shedding is considered in the problem formulation. The consumer energy system consists of two CHP units, one electrical unit, one thermal unit, and a heat buffer tank (HBT) for the storage of surplus thermal energy. The consumer can also buy electricity from the main electricity grid to supply the demanded load based on the price of electricity. The simulation results show that the application of the suggested DRP reduces the operational cost.

This paper aims to investigate the operation and control strategies of a multi-input converter. The interest in this type of topology is becoming higher and its applications more relevant, as the use of energy sources with distinct voltage and current characteristics is diffused. Firstly, the converter was modeled and afterward three controllers have been designed: proportional-integral, fuzzy logic controller and state-feedback. Through simulation analysis, it was possible to validate the obtained model as well as assess the pros and cons from each control strategy employed for the chosen converter.
