Multi‑Agent Cooperative Dispatching Strategy For Distribution Network Considering Shared Energy Storage, Linyao Zhang, Guilian Wu, Jinlin Liao, Xin Hu, Lijun Liu

Journal of Electric Power Science and Technology

In view of the current problems of only single operation mode, vague profit method, and low utilization rate of the energy storage business for power grid, a business operation mode combining self-operated electricity and shared energy storage is proposed. First, a multi-agent collaborative scheduling model of the power distribution network considering shared energy storage is established. This model takes into account the interests of the power distribution network, load aggregators, and energy storage providers, while effectively reducing the peak-to-valley difference of the net load and hence relieving the peak shaving pressure of the power grid. Then, the model implements a …

Maackia amurensis lectins serve as research and botanical agents that bind to sialic residues on proteins. For example, M. amurensis seed lectin (MASL) targets the sialic acid modified podoplanin (PDPN) receptor to suppress arthritic chondrocyte inflammation, and inhibit tumor cell growth and motility. However, M. amurensis lectin nomenclature and composition are not clearly defined. Here, we sought to definitively characterize MASL and its effects on tumor cell behavior. We utilized SDS-PAGE and LC-MS/MS to find that M. amurensis lectins can be divided into two groups. MASL is a member of one group which is composed of subunits that form dimers, …

Faculty Scholarship

Abstract: Laser-powder bed fusion (L-PBF) is a popular additive manufacturing (AM) process with rich data sets coming from both in situ and ex situ sources. Data derived from multiple measurement modalities in an AM process capture unique features but often have different encoding methods; the challenge of data registration is not directly intuitive. In this work, we address the challenge of data registration between multiple modalities. Large data spaces must be organized in a machine-compatible method to maximize scientific output. FAIR (findable, accessible, interoperable, and reusable) principles are required to overcome challenges associated with data at various scales. FAIRified data …

Hierarchical Dispatching Strategy Of Islanded Microgrid Considering Droop Curve And Energy Storage, Keran Li, Jichun Liu, Runlin Yang, Yizhu Liu

Journal of Electric Power Science and Technology

At present, the operation dispatching of distributed generadion (DG) in islanded microgrids is treated uniformly as PQ model of traditional generators, which is inconsistent with the actual situation of microgrids. At the same time, few literatures consider voltage and power flow constraints. Therefore, considering the static model of droop control for DG and taking into account the nonlinear constraints of power flow, a hierarchical scheduling strategy for islanded microgrids with renewable energy output and energy storage charging and discharging is proposed. Meanwhile, considering the droop characteristics of DG and the nonlinear constraints of power flow, the economic and safe operation …

CryoGARS Glaciology Data

Tracking the extent of seasonal snow on glaciers over time is critical for assessing glacier vulnerability and the response of glacierized watersheds to climate change. Existing snow cover products do not reliably distinguish seasonal snow from glacier ice and firn, preventing their use for glacier snow cover detection. Despite previous efforts to classify glacier surface facies on local scales, a unified approach for monitoring glacier snow cover on larger spatial scales remains elusive. We present an automated snow detection workflow for mountain glaciers using supervised machine learning-based image classifiers and Landsat 8/9, Sentinel-2, and PlanetScope satellite imagery. We develop the …
