MES operation is constrained by different kinds of limits, including limits on the components and limits due to the topology of the interconnections and technical aspects concerning the interactions among MES components. This paper presents a novel extension of the optimization model with linear constraints used in the literature to solve the MES optimization with constant efficiencies and coefficients of performance (COP) of the equipment. The extended optimization model considers non-linear convex expressions of the equipment efficiencies and COPs and solves the optimization model with linear constraints in an iterative way, until the solution does not change more than a specified tolerance. The optimal MES solutions are shown considering the operation of a trigeneration system that serves electricity, heat and cooling loads in winter and summer cases with specific demand and energy prices, comparing the solutions with constant and variable efficiencies and COP.","PeriodicalId":397494,"journal":{"name":"2022 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124564868","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 paper implements three deep reinforcement learning algorithms and compares them based on their monetary gain as well as the vehicle battery degradation they cause.

For this purpose, an elderly care center in Ålesund, Norway is chosen as the pilot building. A high spatiotemporal resolution building energy model is developed including thermal zones and energy systems, verified against metered electricity use. The performance of the flexible demand-side management is assessed in relation with the installed PV production, during extreme warm conditions considering 13 future climate scenarios over the 30-year period of 2021-2050. Adaptation measures are applied to respond to the environment variations, providing flexibility while ensuring the thermal comfort of the residents. Results show 22% and 20% peak power and load curtailment, respectively. The discomfort hours are reduced by 22%. The performance of the flexible energy management appears when the PV production is not sufficient for the demand. Therefore, the impacts are on the grid electricity which leads toward a higher grid independency. The most significant change is the peak shaving in the afternoon hours when the grid experiences high loads. Further research is required to evaluate the effectiveness of installing battery system on load shifting.","PeriodicalId":397494,"journal":{"name":"2022 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114733368","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 main reason is that roof-top solar PV sites are usually unobservable by the distribution system operators (DSOs) and consequently their generation is not measured. Therefore, the accurate knowledge regarding the real time generation of the residential PVs will become an imperative need. In this paper, a methodology for estimating the power generated by all the residential PVs of a certain area using the available information from some observable residential PVs is proposed. Considering the high impact of the solar panel orientation on the PV generation, the proposed method clusters together the residential PVs with the same orientation. The results show that there is a maximum reduction in the mean absolute error by 62% in the summer season for 25 degree panel azimuth in comparison to the case that the generation of the unobservable PVs are estimated without using the orientation of the solar panels. The methodology was validated using real data from residential PVs.","PeriodicalId":397494,"journal":{"name":"2022 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127627136","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 uncertainty related to future production costs of the conventional generating units, future consumption levels of the flexible demands, and future energy market prices is modeled using confidence bounds and uncertainty budgets.

PSMP mho relays are used for distance protection of transmission lines. Positive sequence memory polarization is employed to ensure dependable operation during close-in faults. For the PSMP mho elements located on transmission lines energized by synchronous generators (SGs), the memory polarized mho elements experience an expansion of characteristics. This dynamic expansion enhances the resistive coverage of the characteristics, thus improving its dependability. In PV generators, the converter controls determine the magnitudes and angles of fault signals. This paper presents the impact of $P-Q$ control of grid-following PV generators on the dynamic and steady-state behaviour of the PSMP mho characteristics. The has been analyzed with respect to the fault signals governed has been analyzed with respect to the fault signals governed by the $P-Q$ control strategy. Modified IEEE-39 bus system with additional PV generators is simulated in PSCAD software for performance evaluations. Various Zone-1 forward faults and Zone-3 reverse faults have been studied to analyze the dynamic PSMP mho performance. It is observed that for the lines emanating from PV generators, the PSMP mho characteristics lose their resistive reach considerably for both forward and reverse faults. As a result, the dependability of the PSMP mho element also explained in terms of the $P-Q$ control actions during fault.","PeriodicalId":397494,"journal":{"name":"2022 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126781473","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}

Special purpose EVs such as four wheel drive SUVs and all-terrain electric vehicles (ATVs) use multiple motors in their drive train system. Thus, a multi-output inverter with multilevel topology can be employed to decrease the cost and increase the reliability. The traction motors used in EV application need to be controlled in closed loop fashion in order to obtain better dynamic response. In this paper, a three-level dual output voltage (TL-DOV) inverter is presented, that can independently control two three-phase motors in closed loop. The TL-DOV can generate low-ripple current waveforms with controllable amplitude, frequency and phases. The disadvantage of requiring multiple DC sources is also mitigated. Field-oriented control is implemented to control the speed % torque of the permanent magnet synchronous motor (PMSM).
