We also use new weighting functions and time-varying exponential smoothing method to ensure the robustness and improve the forecast accuracy of the distributed state estimation method. At last, an example is used to demonstrate the effectiveness of the proposed algorithm together with the parameter identification.]]> Wed 10 Oct 2018 13:41:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44303 Tue 11 Oct 2022 15:58:53 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37654 Tue 09 Mar 2021 17:51:53 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39947 Thu 30 Jun 2022 14:29:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50051 Thu 29 Jun 2023 15:41:39 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52108 Thu 28 Sep 2023 14:56:46 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39787 Thu 23 Jun 2022 11:11:02 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43267 Thu 15 Sep 2022 11:48:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31315 Sat 24 Mar 2018 08:43:35 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18995 Sat 24 Mar 2018 08:05:36 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21050 Sat 24 Mar 2018 08:00:34 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18951 Sat 24 Mar 2018 07:58:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19153 Sat 24 Mar 2018 07:52:20 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26098 Sat 24 Mar 2018 07:39:52 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28664 Sat 24 Mar 2018 07:37:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28662 Sat 24 Mar 2018 07:37:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26038 Sat 24 Mar 2018 07:26:29 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26035 Sat 24 Mar 2018 07:26:28 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28130 a posteriori (MAP) estimation technique, which delivers a globally optimal estimate under certain assumptions. We apply the distributed approach to an IEEE 118-bus system, and compare it with a centralized approach, which provides the optimal state estimate using all the measurements, and with a local state estimation approach, which uses only local measurements to estimate local states. Simulation results show that under different scenarios including normal operation, bad measurements and sudden load change, the distributed approach is clearly more accurate than the local state estimation approach and distributed static state estimation approach. Although the result is a bit less accurate than that by a centralized algorithm, the distributed algorithm enjoys low computational complexity and communication load, and is scalable to large power networks.]]> Sat 24 Mar 2018 07:24:55 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26907 Sat 24 Mar 2018 07:23:36 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23268 Sat 24 Mar 2018 07:16:59 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22198 Sat 24 Mar 2018 07:16:25 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22188 Sat 24 Mar 2018 07:16:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23282 Sat 24 Mar 2018 07:13:35 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23457 Sat 24 Mar 2018 07:13:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24105 Sat 24 Mar 2018 07:11:45 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24725 Sat 24 Mar 2018 07:10:59 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33118 Mon 27 Aug 2018 18:23:55 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34277 Mon 25 Feb 2019 14:56:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37150 Mon 24 Aug 2020 11:10:58 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40742 Mon 18 Jul 2022 13:19:21 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32189 Fri 11 May 2018 13:24:15 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44126 Fri 07 Oct 2022 14:33:29 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44124 Fri 07 Oct 2022 14:26:37 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47884 Fri 03 Feb 2023 15:59:52 AEDT ]]>
