The system frequency response (SFR) model describes the average network after a disturbance and has been applied to wide variety of dynamic studies. However, traditional literature does not provide generic, analytical method for obtaining SFR parameters when contains multiple generators; instead, numerical simulation-based approach or operators' experience is common practice obtain an aggregated model. In this paper, proposed aggregating multi-machine into single-machine verification study...

Demand response (DR) has been widely recognized as an important approach to balance the power grid and reduce peak load of systems. In order better estimate capability expense reduction through DR, we need obtain residential profile customers' attitudes toward DR programs. Based on a large-scale online survey collected among over 1500 customers from New York Texas in U.S., this paper investigates relationships household appliance activities (e.g., electric water heater air conditioner),...
The smart grid vision has resulted in many demand side innovations such as nonintrusive load monitoring techniques, residential micro-grids, and response programs. Many of these techniques need a detailed network model for their research, evaluation, validation. In to need, this paper presents sequential Monte Carlo (SMC) simulation platform modeling simulating low voltage networks. This targets the quasi-steady-state condition over an extended period 24 h. It consists two main components....
Abstract As a key component of an integrated energy system (IES), storage can effectively alleviate the problem times between production and consumption. Exploiting benefits improve competitiveness multi-energy systems. This paper proposes method for day-ahead operation optimization building-level (BIES) considering additional potential storage. Based on characteristics peak-shaving valley-filling storage, further consideration changes in system’s load real-time electricity price, model is...
Large-scale wind and solar power integration are likely to cause a short-term mismatch between generation load demand because of the intermittent nature renewables. System frequency is therefore challenged. In recent years, it has been proposed that part residential can be controlled for regulation with little impact on customer comfort. This paper proposes thermostatic control strategy primary secondary regulation, in particular, using heating, ventilation, air-conditioning units electric...
Existing models featuring numerous electric vehicles (EVs) for centralized frequency regulation achieved high accuracy at the expense of heavy computational workloads and a real-time communication requirement. This paper develops state space model (SSM) that provides probability to realize power control aggregated EVs with efficiency but low The SSM, reduced based on method, accurately describes different connecting states various state-of-charge (SOC) states. Considering heterogeneous...
High penetration of renewable energy may cause considerable system frequency deviations. Electric vehicles (EVs) offer alternative potentials for regulation with rapid responding speed. However, many EVs under centralized control, existing modeling methods achieve accurate control results at the cost high computational complexity, a real-time communication requirement due to individual signals, and possible disturbances charging preferences. This paper focuses on solving these crucial...

The long-term planning problem formulated as two-stage stochastic mixed-integer programming (SMIP). first stage make decisions of DG siting and sizing under given budget constraint. second stage, post-extreme-event-restoration (PEER) employed minimize operating cost in an uncertain fault scenario. particular, study proposes method...
We discuss the impact of cultural differences on usability evaluations that are based thinking-aloud method (TA). The term 'cultural differences' helps distinguish in perception and thinking Westerners (people from Western Europe US citizens with European origins) Easterners China countries heavily influenced by its culture). illustrate cognition four central elements TA: (1) instructions tasks, (2) user's verbalizations, (3) evaluator's reading user, (4) overall relationship between user...
The increasing integration of renewable resources and electric vehicles (EVs) presents new requirements for the construction a current distribution network. As an alternative conventional network, active network (ADN) has gained more interest its flexibility interactivity. However, unpredictable behavior ADN participants from source-side, network-side, demand-side brings challenges on dispatch. Thus, it is urged to design optimal scheduling approach that can comprehensively regulate...
Within the deregulation process of distribution systems, locational marginal price (DLMP) provides effective market signals for future unit investment. In that context, this paper proposes a two-stage stochastic bilevel programming (TS-SBP) model investors to best allocate battery energy storage systems (BESSs).

The rapid increase in renewable energy integration brings with it a series of uncertainty to the transmission and distribution systems. In general, large-scale wind solar power always cause short-term mismatch between generation load demand because their intermittent nature. traditional way dealing this problem is spinning reserve, which quite costly. recent years, has been proposed that part can be controlled dynamically for frequency regulation little impact on customers' living comfort....
As the penetration of renewable energy continues to increase, stochastic and intermittent generation resources gradually replace conventional generators, bringing significant challenges in stabilizing power system frequency. Thus, aggregating demand-side for frequency regulation attracts attentions from both academia industry. However, practice, aggregation approaches suffer random uncertain behaviors users such as opting out control signals. The risk-averse multi-armed bandit learning...

The worldwide severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak has led to the rapid spread of disease (COVID-19). quantitative real time PCR (qPCR) is widely used as gold standard for clinical detection SARS-CoV-2. However, more and infected patients are relapsing after discharge, which suggests qPCR may fail detect virus in some cases. In this study, we selected 74 samples from 43 recovering inpatients Droplet Digital (ddPCR) synchronous blind detection, established a...
