Solar power is a kind of clean and renewable energy, which can be utilized in the industrial micro-grid as an effective approach to decrease energy costs and reduce the emission of greenhouse. However, the uncertainty of solar power together with the limit of thermal power units' adjustment ability will bring a great challenge to keeping balance of power demand and supply. In this paper, the storage...
With the control technology development of household load and smart grid, household microgrid energy optimal scheduling will be an important means to provide personalized, differentiated electricity services for users. Based on the different characteristics of household microgrid load, models are established for fixed load, shiftable load and adjustable load in this paper. Considering the comfort...
This paper proposes an improved power sharing control scheme to achieve the accurate power sharing control and offer an improved PCC voltage regulation capability in islanding microgrid. An enhanced virtual impedance design is assumed in the conventional droop control scheme to manage distributed generation (DG) units to export the accurate reactive power in proportion to their rating. A point of...
Residential load scheduling is of great significance for the building energy saving. But it is difficult for current methods to discover and consider the relationship between the various comfort requirements and uncertain load demand of customers. In this paper, a new method for the residential load scheduling based on load behavior analysis is proposed to reduce the electrical cost while considering...
With the development of wind power, how to use wind power fully has become an important research. In this paper, wind power accommodation robust model with security constraints considering demand response is built to accommodate wind power as much as possible. The robust model is a two-level optimal model: the upper level is to minimize the curtailed wind power and the lower level is to re-schedule...
According to the high efficiency, high reliability requirements in Body Control Module (BCM) function test, an idea of automated test is proposed. Based on one platform of BATC high-end passenger-car, and combined with the BCM CAN/LIN network environment, the design of an automated test system is completed by means of industry personal computer (IPC), bench, VT System, programmable power supply, Connector...
As a precondition for accurate equipment failure positioning, a battlefield damage assessment performs an important role in quick fault correcting and efficient fighting ability recovering. This paper, with the missile loading vehicle hydraulic system of a certain type as an example, introduces the general analysis process in battlefield damage assessment of items as the basic functional project,...
It is important for both energy intensive enterprises (EIEs) and the utilities to analyze the electrical load tracking capacity of EIEs, so as to utilize resources in EIEs, and promote the participation of EIEs in Demand Response (DR) programs. An electrical load tracking problem integrating power generations self-scheduling (PGSS) and flexible load adjustment (FLA) is introduced. The relationships...
Wind shear and tower shadow makes wind speed in the rotor rotating plane changing differently, so it increase the load difference of every blade seriously. This paper model 1.5MW wind turbine for individual pitch control, and analyze the main reason of periodic load fluctuation. Then individual pitch control based on load calculation was researched combining the actual of the load is difficult to...
ERCOT has moved from a zonal market to an advanced nodal market since December 2010. In ERCOT, combined cycle trains (CCT) contribute a significant share of its total installed capacity. Therefore, how to accurately and efficiently model the CCT is one of the key factors for a successful EROCT nodal market. In order to facilitate market operations and ensure the system reliability, the ERCOT nodal...
In the smart grid environment, appropriate power energy exchange strategies will be necessary for energy intensive industries (EIIs) with industrial power plants. This paper presents a systematic approach that can cope with the integration of industry consumers and an energy exchange strategy aiming at achieving balance between power production and consumption in EIIs. A basic balance model using...
The interface damage of single solder joint was simulated using cohesive zone model incorporated in finite element analysis. In this study, the solder/IMC/Cu pad interfaces models were constructed for the molecular dynamics simulation. The traction-separation law was derived when the interface model was subjected to a principle strain in one direction. The materials properties of cohesive element...
The interfacial failure behavior of a single solder joint is investigated under the pure tensile or shear loading at 5 mm/s. The brittel failure is detected for the specimen under pure tension loading, while a ductile failure is found after pure shear loading. A cohesive zone model is employed herein to explore the dynamic fracture behavior at the solder/IMC and IMC/Cu pad interfaces. The simulated...
