This paper investigates the optimal procurement and scheduling of battery storage a in distribution system with high photovoltaic (PV) penetration. The battery under study is assumed to be owned by private entities with the objective of minimizing the electricity bill (or, interchangeably, maximizing the PV system yields). Voltage regulation is achieved by controlling the net metered real power at the point of common coupling of (PCC) of each entity. Dynamic energy conversion equation is used to model the battery with the impact of cyclic aging considered. The procurement-scheduling problem is formulated as a nonlinear programming (NLP) problem. A recursive method is proposed to determine the lifetime of the battery. The proposed methodology is validated on the IEEE 33-bus feeder system. A thorough economic analysis is conducted to quantify the financial benefits brought in by battery.

This paper describes a reference architecture for a reusable and extendable solution for a Self Healing Grid (SHG) applied to looped distribution networks. This functionality is also known as automatic Fault Location Isolation and Supply Restoration (FLISR). The paper will report on the experience of testing and installing several such systems particularly on underground networks.

With the growth in the number of PMUs in the electrical system, the discussion and understanding of performance requirements required in IEEE standard C37.118.1-2011 and its addendum IEEE C37.118.1a-2014 is of fundamental importance for the future specification, operation and maintenance of future interconnected power grids. This paper presents an analysis of two different algorithms for calculating synchrophasors in accordance with limits and test methods proposed in the IEEE standard. Results are presented using a hybrid simulation platform, in which the algorithms are implemented in a real PMU.

Dynamic demand response (DR) is an integral part of ancillary services markets. The integration of dynamic DR control loop into the conventional load frequency control (LFC) model is presented by the authors in [1]. Extensive analytical analyses were carried out on single-area power system in previous study. In this paper, the idea is expanded to a general multi-area interconnected power system. Then, impacts of the proposed LFC-DR on the dynamic performance of the multi-area power systems in different conditions are simulated. Simulation results show a superior performance of the LFC-DR model for different conditions and power system models.

A new approach to achieving volt-var control through the use of fast-acting distributed hybrid power electronics devices at the grid edge is proposed. It is shown that there is a missing layer of control at the grid edge which the conventional approaches do not address. Through field demonstration of 91, 10 kVAR devices on a 13 kV, 6 MW feeder, up to 5% CVR, 72% reduction in voltage volatility, 80% reduction in voltage unbalance and feeder level dynamic var control using the proposed grid edge control is presented.

Ground fault over-voltage (GFOV) study is an indispensable utility planning study for circuits with high penetration of PV. This paper presented mechanism of GFOV on sub-transmission circuit and distribution circuit caused by both rotating machine generation and PV inverter generation. GFOV on a real sub-transmission circuit with different penetration level of PV was modeled and simulated in PSCAD/EMTDC. Simulation results were analyzed according to the voltage arrester TOV curve as sub-transmission level study criteria and ITIC curve as distribution level study criteria. Based on comparing GFOV caused by rotating machine generation and by PV inverter generation, analysis results were discussed in detail. GFOV mitigation measures were also discussed in this paper.

This paper proposes to enhance existing power flow solutions for application in multi-frequency AC power systems. The paper shows such power flow solutions can be obtained using existing methods provided that impedances of lines operating at different frequencies be reflected to their equivalent impedances at the fundamental power frequency. The paper first presents a mathematical proof of equivalent parameters in terms of power flow of a transmission line operated at a low frequency and the fundamental frequency. It is then validated by analyzing the power flow solutions of a power system modeled in PSCAD/EMTDC when it is operated at multi-frequency and at conventional 60 Hz conditions. An application of a low frequency AC transmission line is illustrated to demonstrate its superiority in terms of power carrying capacity over a typical fundamental-frequency AC transmission line.

Summary form only given. Development of distributed energy resources (DER) introduces high level of interdependency and the need for integrated models in a multi-energy system (MES). Moreover, highlighting environmental aspects facilitates electrification in the transportation sector and integration of plug-in electric vehicles (PEV). In this paper, aggregation of PEVs' batteries in parking lots (PL) is considered as a bulk electric storage in MES. The energy hub approach is employed for modeling MES considering PL. Due to the profitable behavior of PL in the reserve market, the energy hub model is modified to consider the reserve sources as ancillary services in the output energy vector. Moreover, the uncertain traffic pattern of PEVs' owners in PL is modeled by a stochastic approach. The numerical results demonstrate the proficiency of the proposed model, determining the changes in the behavior of other MES's elements in the presence of PL.

Probabilistic considerations of uncertainties in distribution grid planning is one of the keystones to avoid oversizing of grids and equipment due to unreal worst-case assumptions. However, the computational costs to integrate uncertainties in calculation processes reach from worth mentioning to unfeasible. In this paper, a new method is introduced, which consists of a simplification and a rank comparison process and yields high accuracy as well as low computational costs. Various DER control strategies and nonlinear network equipment can be integrated and time savings of up to a factor of 9000 can be reached.
