This paper presents an enhanced centralized voltage control method utilizing real-time satellite-observed solar radiation data for distribution networks with PVs. Conventional centralized voltage control methods cannot prevent voltage deviation between data acquisition periods when large voltage fluctuation occurs because of PV output fluctuation. This is because the tap positions are determined regardless of PV output although there is few risk of large voltage rise/drop when PV generates full/no power. The proposed method forecasts voltage fluctuation width by utilizing the real time solar radiation data, which are acquired every 30 minutes at grid points with a 1 km resolution, and determines tap positions of an on-load tap changer and step voltage regulators to maximize the minimum voltage margin between the forecasted voltage and the voltage limits. The numerical simulation utilizing actual measured PV output profile and solar radiation data will show that the proposed method enhanced the voltage control effectiveness.

Several countries are encouraging the installation of distributed generation units with great success. The connection of these units to the existing electrical system gives rise to new challenges relating to the operation of the electrical system and operation of the protection. Thus, several recent studies suggest techniques to define the best protection settings to ensure coordination and selectivity of the protection system. This article will present the biggest problems that arise with the connection of distributed generation units to the electrical system, and will also present the state of the art techniques used to change the settings of the protections aimed at accommodating the changes that distribuited generation require to the electric system operation.

This paper evaluated the impact of smart inverter Volt-VAR function on voltage reduction energy saving and power quality in electric power distribution systems. A methodology to implement the voltage reduction optimization was developed by controlling the substation LTC and capacitor banks, and having smart inverters participate through their autonomous Volt-VAR control. In addition, a power quality scoring methodology was proposed and utilized to quantify the effect on power distribution system power quality. All of these methodologies were applied to a utility distribution system model to evaluate the voltage reduction energy saving and power quality under various PV penetrations and smart inverter densities.

A modular microgrid unit (MMGU) is a packaged microgrid that can work autonomously but is also capable of connecting to other MMGUs to form an expandable microgrid. It is flexible and can be implemented with different resources, such as hydropower or wind. An MMGU's power electronic interface accompanied with battery storage unit provides a high level of stability, which is critical in microgrids. A key factor when implementing an MMGU is to determine appropriate MMGU component ratings to match physical characteristics of available resources. This paper discusses the application of an MMGU in a pumped-storage unit. The main components of MMGU are introduced and equations are presented to find rating of these components. Then, typical MMGU component ratings for a 250-kW system are calculated and the feasibility of the design is assessed.

In this paper, the performance and transient frequency response of an islanded microgrid with two different categories of inverters are analyzed when different control set-point signals are defined for the Current Source Inverters. Voltage Source Inverters (VSIs) use a decentralized droop controller which helps preserving the power-sharing stability. Then, Current Source Inverters (CSI, also called PQ inverters) will improve the system's performance by providing extra capacity for the system to accommodate load changes. In this context, defining proper active and reactive power set-points for CSI (PQ) inverters of a microgrid is one of the necessary control designs that ensures systems integrity by providing more secure power supply to the loads. The study conducted here tries to propose different possible solution for communication link selection and definition in order to form an appropriate set-point signal. Consequently it minimizes the need for communication links as much as possible while making sure that the systems performance is acceptable. The proposed control signals are investigated and their effects on the transient response are demonstrated using an 11 bus microgrid.

Heating, ventilation, and air conditioning (HVAC) systems in commercial buildings can provide ancillary services (AS) to the power grid, but by providing AS their energy consumption may increase. This inefficiency is evaluated using round-trip efficiency (RTE), which is defined as the ratio between the decrease and the increase in the HVAC system's energy consumption compared to the baseline consumption as a result of providing AS. This paper evaluates the RTE of a 30,000 m2 commercial building providing AS. We propose two methods to estimate the HVAC system's settling time after an AS event based on temperature and the air flow measurements from the building. Experimental data gathered over a 4-month period are used to calculate the RTE for AS signals of various waveforms, magnitudes, durations, and polarities. The results indicate that the settling time estimation algorithm based on the air flow measurements obtains more accurate results compared to the temperature-based algorithm. Further, we study the impact of the AS signal shape parameters on the RTE and discuss the practical implications of our findings.

Online Dynamic Security Assessment (DSA) is a dynamical system widely used for assessing and analyzing an electrical power system. The outcomes of DSA are used in many aspects of the operation of power system, from monitoring the system to determining remedial action schemes (e.g. the amount of generators to be shed at the event of a fault). Measurement from supervisory control and data acquisition (SCADA) and state estimation (SE) results are the inputs for online-DSA, however, the SE error, caused by sudden change in power flow or low convergence rate, could be unnoticed and skew the outcome. Therefore, generator shedding scheme cannot achieve optimum but must have some margin because we don't know how SE error caused by these problems will impact power system stability control. As a method for solving the problem, we developed SE error detection system (EDS), which is enabled by detecting the SE error that will impact power system transient stability. The method is comparing a threshold value and an index calculated by the difference between SE results and PMU observation data, using the distance from the fault point and the power flow value. Using the index, the reliability of the SE results can be verified. As a result, online-DSA can use the SE results while avoiding the bad SE results, assuring the outcome of the DSA assessment and analysis, such as the amount of generator shedding in order to prevent the power system's instability.

Massive introduction of electric vehicles (EV) generates opportunities and challenges for society. In this way, a new entity of electricity markets which have to manage electric vehicles charging is needed, the aggregator. This paper proposes a smart charging for an EV aggregator which uses a user tariff preference. Users will select between three different tariffs and the aggregator will modulate charging power rate in order to optimize charging costs. The aggregator will also take into account a charging pattern given by Distribution System Operator (DSO) and Transmission System Operator (TSO), and the energy desired by each user.

Classification of electrical loads presents multiple benefits. From the ability to inform customer how their appliances contribute to the overall electricity cost, to allowing electric companies and virtual aggregators to institute demand response mechanisms. In this paper we propose a new type of active sensing method which breaks down real-time data into fixed segments which can be quickly analyzed and used to classify electrical loads to help reduce peak power demand. We have designed and implemented a simple smart plug with a bidirectional triode thyristor, gathered data from household appliances and performed classification. Our results show high accuracy with significantly shorter times than other similar proposed methods.
