In view of the coordinated control and scheduling of distributed energy, such as controllable units, energy storage devices and fans in distribution networks, a virtual power plant source and load storage optimization scheduling model with uncertainties, demand response and network security constraints under centralized control is proposed. Firstly, the wind turbine, gas turbine, energy storage battery and load are integrated into a virtual power plant, and price-type demand response measures are implemented on the user side to improve the load curve. Then, aiming at maximizing the operating profit of the virtual power plant, the opportunity constraint model is used to describe the uncertainty of the wind turbine, load forecasting and internal power balance, and consider the operational constraints and network security constraints of each unit. The scheduling scheme is generated based on the reasonable control and coordination of the output of each component. Finally, the quantum particle swarm optimization algorithm with inertia weight adaptive adjustment is used to solve the model. The feasibility of the model and the effectiveness of the algorithm are verified by an example analysis of the IEEE 9 node improved system.
With the rapid adoption of intermittent energy sources, HVDC transmission plays an increasingly significant role in power systems. To optimize the utilization of AC/DC grids with a high share of RES, there is a critic...

This paper proposes a stochastic programming approach to the solution of sizing problem of energy storage system applied to grid-connected wind power plants. The objective is to maximize expected daily profit though time shifting of renewable energy production. The problem is formulated considering stochastic behaviors of renewable power as well as electricity prices. We apply stochastic programming framework with Sample Average Approximation (SAA). We conduct a case study using data from the Electric Council Reliability Council of Texas (ERCOT). It is shown that considerable profit can be achieved with a suitable energy storage size.

Sustainable chemical process design can be formulated as a multi-objective optimization (MOO) problem covering economic, environmental and societal aspects. Moreover, uncertainties are unavoidable during the process design. So, uncertainties should be involved in the optimization. In this work, authors work on the basis of stochastic programming to deal with uncertainty factors, and integrate MOO deterministic algorithms to identify the optimal process design for the improvement of sustainability from a number of alternatives. The efficacy of the procedure is demonstrated by design of 1-hexene separation process.
