TL;DR: A novel bidding strategy for PEVs offering V2G by including the projected battery degradation cost to integrate them into microgrid operation and two energy management strategies are proposed for inclusion of V1G into the micro grid operation based on the forecast accuracy on energy supply and demand, and market prices.
Abstract: In modern electric power systems, plug-in electric vehicle (PEV) with vehicle-to-grid (V2G) potential are becoming reliable and flexible resources for energy balancing under varying energy supply and demand scenarios. In this evolving paradigm, designing energy management strategies for feasible and cost-effective utilisation of V2G is one of the several challenges faced by the utility operators and regulators. This paper proposes two energy management strategies to effectively utilize V2G potential of PEVs in managing energy imbalances in grid-connected microgrids. The contributions of this paper are in twofold. First, it proposes a novel bidding strategy for PEVs offering V2G by including the projected battery degradation cost to integrate them into microgrid operation. Second, two energy management strategies are proposed for inclusion of V2G into the microgrid operation based on the forecast accuracy on energy supply and demand, and market prices. The proposed V2G integration strategies are implemented using a multi-agent system developed in Java agent development framework and applied to a microgrid case study system. The simulation results and their analysis show that V2G can be used to maximum depth of discharge levels if the electricity price variation is high and battery cost of PEVs is low.

TL;DR: In this paper, a utility theory model for bid markup determination is developed using 21 criteria in the bidding decision, and the majority of the criteria are evaluated subjectively by a decision maker, and numerical quantification and evaluation is typically difficult for such criteria.
Abstract: A utility theory model, which is one of three generic methods for bid markup determination, is developed using 21 criteria in the bidding decision. The majority of the criteria are evaluated subjectively by a decision maker, and numerical quantification and evaluation is typically difficult for such criteria. Previous works of Saaty, Lifson and Shaifer, and Ahmad and Minkarah are used to develop a simplified approach using straight-line utility functions to resolve such difficulty. This bidding model accommodates the variation of different decision makers' attitude in the weighting of criteria, and thus the model can be customized to different preferences and bias of risk. Considering the subjectivity of the process, the writers consider the accuracy of this approach to be acceptable for the use of utility theory as one of the decision making tools that are available to assist the construction contractor in determination of bid(s) markup during bid preparation.

TL;DR: In this paper, the authors describe interrelationships between engineering design, construction, and operation costs for a facility, and show how the "level of influence" over those costs decreases precipitously as the project evolves.
Abstract: This paper describes interrelationships between engineering design, construction, and operation costs for a facility, and shows how the "level of influence" over those costs decreases precipitously as the project evolves. The level of influence is by far the greatest during engineering and design, while actual expenditures at that stage are relatively small. The level of influence concept can be helpful in forming contractual arrangements that minimize the suboptimization of costs for one party at the expense of overall project costs and benefits. Contractual arrangements should be drawn so as to assure that current construction and operations knowledge will be injected in the design process. "Construction Management" and "design-construct", if appropriately tailored to the needs of a particular situation, can be helpful for this purpose. A second important conclusion is that efforts to suboptimize design costs by requiring competitive bidding for professional servics are likely to produce much higher project costs in the long run.

TL;DR: The knowledge-based theory of the firm suggests that, as knowledge intensity increases, knowledge management concerns, not opportunism, should increasingly drive organizational boundary decisions as mentioned in this paper, which is not the case here.
