Massive access of renewable energy has prompted demand-side distributed resources to participate in regulation and improve flexibility of power systems. With large-scale access of massive, decentralized, and diverse distributed resources, demand-side market members have transformed from traditional “consumers” to “prosumers”. To explore the distributed transaction model of prosumers, in this paper, a multi-prosumer distributed transaction model is proposed, and the Conditional Value-at-Risk (CVaR) theory is applied to quantify potential risks caused by the stochastic characteristics inherited from renewable energy. First, a prosumer model under constraints of the distribution network including photovoltaic units, fuel cells, energy storage system, central air conditioning and flexible loads is established, and a multi-prosumer distributed transaction strategy is proposed to achieve power sharing among multiple prosumers. Second, a prosumer transaction model based on CVaR is constructed to measure risks inherited from the uncertainty of PV output within the prosumer and ensure safety of system operation in extreme PV output scenarios. Then, the alternating direction multiplier method (ADMM) is utilized to solve the constructed model efficiently. Finally, distributed transaction costs of prosumers are distributed fairly based on the generalized Nash equilibrium to maximize social benefits. Simulation results show the multi-prosumer distributed transaction mechanism established under the proposed generalized Nash equilibrium method can encourage power sharing among prosumers, increasing their own income and social benefits. Also, the CVaR can assist decision making of prosumers in weighting the risks and benefits, improving system resilience through energy management of prosumers.

Detumbling operation toward a rotating target with nutation is meaningful for debris removal but challenging. In this study, a deformable end-effector is first designed based on the requirements for contacting the nutating target. A dual-arm robotic system installed with the deformable end-effectors is modeled and the movement of the end-tips is analyzed. The complex operation of the contact toward a nutating target places strict requirements on control accuracy and controller robustness. Thus, an improvement of the tracking error transformation is proposed and an adaptive sliding mode controller with prescribed performance is designed to guarantee the fast and precise motion of the effector during the contact ***, by employing the proposed effector and the controller,numerical simulations are carried out to verify the effectiveness and efficiency of the contact detumbling toward a nutating target.

The microstructure, mechanical property and corrosion behavior of the AlSi10Mg alloy fabricated by selective laser melting(SLMed-AlSi10Mg) after different post heat treatment(PHT) of direct aging(DA), solid solution(T4)and solid solution + aging(T6) were investigated. The microstructural characterization revealed that the porosity of the SLMed-AlSi10Mg was increased from 0.41 ± 0.04 % to 3.09 ± 0.11 % with increasing temperature. The Asbuilt and DA-treated samples exhibited a microstructure of α-Al matrix surrounded with continuous Si networks,whereas the T4-treated and T6-treated samples presented a microstructure of α-Al matrix surrounded with discrete Si particles. The microhardness, strength and work hardening rate of the SLMed-AlSi10Mg increased in the order of T4-treated sample < T6-treated sample < As-built sample < DA-treated sample(a reverse order was found for the elongation), which was due to the precipitation of nanoscale Si particles after DA treatment and the softening of α-Al matrix after T4 and T6 treatments. The corrosion resistance of the SLMed-AlSi10Mg was obviously deteriorated after T4 and T6 treatments compared with DA treatment, which was caused by the changes in Si morphology, residual stress and porosity.
