{"title":"Ensuring stability in a multi-zone MVDC shipboard power system","authors":"Seth Cooper, H. Nehrir","doi":"10.1109/ESTS.2017.8069310","DOIUrl":"https://doi.org/10.1109/ESTS.2017.8069310","url":null,"abstract":"Naval ship power systems are evolving towards more electronics, more “vital” electronic systems, and a larger percentage of the overall energy load needed in the form of electricity. This is due to larger load demands from sensors, future weapons systems, and electrified propulsion. New technologies, such as All-Electric Ships, Integrated Propulsion Systems, and DC-Microgrids, the combination of which is referred to as MVDC, bring the promise of greater flexibility in design and operation, improved system resiliency, and increased energy efficiency. These advancements, however, depend on power electronic devices to control power flow and ensure voltage stability. At points in the power network, power electronic devices can behave as constant power loads (CPLs), which exhibit negative impedance, and at other times can demand large, instantaneous pulses of power. An improperly designed MVDC will become unstable amid large swings in power demand, and the voltage will collapse bringing the entire system down. Through a hierarchical control structure, where ensuring that system stability is maintained at a different level of control than the optimization of the power flow, these challenges can be understood and overcome separately. Different system goals are accomplished at each level in the control hierarchy, and each higher level of control is executed on a successively slower time scale. At the lowest level are current and voltage control for each of the above mentioned devices. The next level involves droop control on the current and voltage set points to ensure stability and up to the moment power balance, and ensures proper voltage regulation at each bus, and the third level focuses on optimization of resources. This paper focuses on the middle level, establishes stability criteria using non-linear techniques, and demonstrates the feasibility using numerical simulation.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122028918","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}

However, the thrust and power consumption of the thrusters are low during DP operation. In this study, the loss energy during one month is investigated. The distribution of the loss energy is shown as a function of speed and power. The results show that considerable losses are occurring at low speed and power. This motivates the need to optimize drivetrain for operational profiles, instead of optimizing them for full load operation.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"307 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120939208","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}

In order to meet the transient and steady power demand of the medium voltage direct current (MVDC) power system of the all electric ship (AES), a hybrid energy storage system (HESS) consisting of a battery as high energy density storage and a supercapacitor as high power density storage is used to support the MVDC power system of the AES. In this paper, a Fuzzy Logic (FL) controller based energy storage management (ESM) system is designed which manages energy storages under different loading conditions. For maintaining the AES's bus voltage within the limit and keeping pace with the load power demand, the ESM system provides reference power for controlling the operations of the energy storages. To demonstrate the effectiveness of the energy storages and load management program, a 12kV MVDC power system of AES is designed with gas turbine based generators, modular multilevel converters (MMC), propulsion systems, service loads, pulsed load, energy storages (battery and supercapacitor), and dual active bridge (DAB) converters in SimPowerSystem. Simulation results are provided to show that the operation of the energy storages. FL control can perform effectively even with variation in the load demand.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121191630","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}

Designing such converters through multi-objective optimization is of interest, because such an approach allows the trade-off between competing objectives (for example, mass and loss) to be explicitly and quantitatively identified. However, doing so can require 104–106 time domain simulations in order to rigorously explore the design space. In this work, a computationally efficient simulation is developed to estimate the MMC waveforms. While the existing literature sets forth average-value models for transient studies of MMCs, fast waveform-level models are still needed. This work presents a suitable approach which is validated against a detailed simulation model.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116366050","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}
