The increase in distributed energy resources (DERs) allow for the increase in microgrid solutions to be implemented in order to ensure uninterruptible supply solutions in areas where system reliability poses as a challenge. This includes electrification of rural networks and islanding solutions where the implementation of highly intrusive electrical infrastructure is not technically feasible or economically justifiable. This paper investigates the potential scalability and replicability effects on the system architecture concept of an island microgrid based on renewable energy resources (RES), battery storage and demand side management (DSM) in order to provide a self-sufficient islanding system. This scalability and replicability analysis (SRA) is done within the InterFlex project. The main objective of the SRA is to scale the microgrid system in order to achieve a theoretical minimum islanding duration of 21 consecutive days based on the existing boundary conditions imposed on the French islands of Lérins. This is achieved through the simulation of the behavior of the network model when these parameters are ‘stressed’. Thereafter, the analysis combines the results to provide a proposed solution based on a worst-case analysis. The paper also investigates the possibility of developing a business model based on the amount of additional flexibility which is available whilst ensuring that the 21 days of islanding duration is sustained. Seasonality is also included in order to observe the dependency of the system variations throughout the year. The results obtained showed that an islanding duration of 21 days is theoretically possible using the well-sized assets. However, the overall system (PV + storage systems) would likely be too cumbersome to be installed on the islands, even with the inclusion of a DSM techniques.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116905063","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}

Based on the outcome of the Pugh Matrix, we select two different approaches for prototypical evaluation. All of them are privacy-preserving and are easy to implement and deploy. For the most suitable approaches, namely passive infrared (PIR) and millimeter waves (mmWaves) technology, a detailed evaluation is conducted.

The estimation of the load equivalent resistance seen before the bridge rectifier in the secondary circuit is crucial for the optimal design of this kind of systems. Generally, the equivalent load resistance model assumes the LC-filter capacitor large enough to neglect the ripple component of the current that flows into the battery. This paper investigates if the above assumption is still correct when the designer chooses a smaller value of the output capacitor, in order to maximize the power transfer at the expense of a nonoptimal efficiency and a larger ripple in the battery voltage and current. The load equivalent resistance was calculated by means of LTSpice simulations in this specific case. The results are compared to those obtained by the typical model generally used in the literature. They show that the development of a new analytical model to extract the load equivalent resistance is required to justify the large difference found.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125570803","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}

Excessive voltage reductions due to heavy demand or over voltage conditions due to production that exceed the local demand can be solved by exploiting control actions as the load shedding or the generation curtailment. The cost of these services, offered by players connected to the MG/LEC, have to be included in the total operational MG/LEC cost. Forecasting in advance, i.e. one day ahead, the state of the network, and the possible contingencies that may happen during the real time, can result in significant savings for the MG/LEC management system, because it is generally assumed that these services are more expensive in the real time than if purchased/planned in advance. Thus, one of the requirements of an optimal MG/LEC management system is to accurately model the local production and demand for making proper decisions in advance, that at least may be slightly changed if the forecasting does not happen in real time. Typical day load profiles that reproduce, in the best possible way, the behavior of the customers can be used for making this task more accurate. This paper compares the impact of using different sets of typical load profiles on the optimization performed by an Energy Management System (EMS), that controls the local MG/LEC resources for solving contingencies. The proposed case study is constituted by a LV MG/ LEC, derived from a real network and it is managed by an EMS based on a multi agent system.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134635962","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}
