The approach first computes the maximum allowed overloading times for the congested transmission lines and transformers, using their dynamic thermal models. Afterwards, the OPF analysis is performed to identify the maximum lead time available to the network operator for managing post-contingency constraints and for devising and implementing the most efficient corrective actions. The corresponding OPF problem is modelled as a mixed-integer nonlinear optimization problem and solved using mixed-discrete particle swarm optimization (MDPSO) approach. The approach is illustrated on a modified IEEE 14-bus network and obtained results demonstrate that presented approach can manage considered constraints within the available lead time.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130284925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Droop control is employed to ensure the proportional power sharing between the parallel inverters while an inherent current-limiting property is achieved through the control design. The current limitation is mathematically proven using nonlinear analysis of the closed-loop system which leads to the boundedness of each inverter current under a threshold value at all times. Furthermore, small-signal analysis is performed to examine the closed-loop system stability of two parallel inverters equipped with the proposed controller. The example of two parallel inverters is further exploited to validate the proposed controller through Matlab/Simulink simulation results.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128414627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach is aimed at savings maximization by minimizing the energy consumption cost of electricity consumers. The core of the approach consists of data clustering in order to forecast demand for the benefit of DSM decisions by incorporating alternate profiles through extended kmeans algorithm, Taylor series linearization and particle swarm optimization. Two cases including integration of PV generation are simulated using the Irish data of more than 5000 smart meters. Different demand flexibility levels are considered in different Scenarios. The paper argues that inherent non-linearity of raw profiles, is likely to provide suboptimal DSM solutions against electricity consumer cost savings, however the uniformity and smoothness of reshaped alternate profiles are more likely to provide optimal DSM solutions, providing electricity consumers a true benefit for their participation in the DSM process.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127569231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has encouraged governments worldwide to fund the development of ultra-low carbon emission vehicles and replace internal combustion engine (ICE) vehicles with electric vehicles (EVs). Among EV drivers, ‘range anxiety’ is one of the main issues resulting from long charging durations. The reduction of charging duration by the introduction of DC fast/rapid charging stations is widely discussed in the literature. However, high charging demands due to fast charging stations may cause some challenges for power networks. In this paper, the impacts of different types of fast chargers on a UK generic distribution network are investigated. The most suitable and robust connection points of the network where fast chargers can be deployed are identified without affecting the stability and security of the system. The main findings show that network losses increase, voltages operate beyond strict limits, and system equipment becomes overloaded with increased fast charging activities in the network. Therefore, critical network points are reinforced with distributed generation units (DG) and static var compensator (SVC) devices to improve the system reliability and mitigate the impacts of such challenges.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115571468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Energy storage has a key role in achieving this task and batteries are the most suitable candidate. In this paper, a complementary solution is presented where excess electricity is used in a cold storage to produce ice which, when melting, supplies the cooling demand. A detailed model of each component is considered in order to simulate the operation of the entire system. The goal of this paper is the derivation of the optimal size of the different components to yield the minimum levelized cost of electricity. The methodology described is applied to a real case study in Marrakesh, and results illustrate that cold storage is able to reduce the total cost of energy in the context of an isolated microgrid.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130792004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By switching off select lines, the system operator can create smaller, easier to control islands. An algorithm for ICI should be fast to implement in real time, as well as capable of integrating islanding requirements such as coherency of the generators in an island and minimum disruption of the power balance caused by the switching of lines. In this work, we approximate the solution to a common ICI formulation by employing a combinatorial approximation scheme of the normalized cut. This approach is easily implementable and numerically robust, exhibits high computational efficiency and allows for a natural integration of islanding requirements (such as generator minimum load and inflexible lines) into the problem solution. Experimental results on systems with up to 3000 buses verify the effectiveness of our approach.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129504246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A wide range of PLC technologies is used for different applications, ranging from home automation to internet access. Various data rates and frequencies are used in different situations. Records of transmitting commands using PLCs have been verified since 1838, and from 1913, technology has become commercial. Currently, communication in low voltage networks is a key technology for the automation of electrical distribution, also known as smart grids. PLC systems can be divided into groups according to the frequency bands and their architecture can be divided into three blocks: PLC, Outdoor and Indoor, which is the focus of this article.

This paper describes and demonstrates an approach to quantitative vulnerability analysis applied to HVDC contingencies. We consider four barriers' ability to mitigate severe frequency drops: inertial response, frequency containment reserves, demand-side response and under-frequency load shedding. Demand-side response, implemented as fast reduction in loads in response to decreasing frequency, is given particular attention. The consequences of an HVDC contingency in the presence or absence of these barriers is analysed to assess the power system vulnerability. Results illustrate how in low-inertia operating states, a) large-scale load shedding may be inevitable after simultaneous outage occurrence of multiple HVDC interconnectors and b) that barriers may significantly reduce the amount of load shed. Demand-side response could be an effective barrier if the response time is low and a sufficiently large amount of load is involved.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132262365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
