A bi-level generation-network-energy storage coordination programming model of an active distribution network (ADN) considering the uncertainty of hydro and photovoltaic (PV) is proposed. Take advantage of the flexible output characteristics of hydropower generators to optimize the installation capacity and siting of distributed PV from the perspective of optimal operation of hydro-PV complementary systems. The upper level of the model is to minimize the comprehensive cost to make decisions on locating and sizing distributed generations (DG) and energy storage. The lower level, with annual operation and maintenance costs and fast voltage stability as the objectives. The economic dispatching of the ADN is realized by taking into account the output of DGs, hydro-PV complementary systems, and the charging and discharging of energy storage. Two-level PSO with a local search algorithm is used to solve this model in a simplified 51-bus distribution network in a region of Yunnan. The simulation results show that the proposed method can effectively reduce the investment cost and operation cost of the ADN, and improve the current problem of low voltage quality under the Yunnan distribution network.

This paper is to present modeling and control of a designed delta planar robotic manipulator. We address the system modeling issue from mathematical models to physical models in Simulink. Inspired by the path following control problem as studied in [1], we show a point-to-point regulation design. Particularly, we embed a high-gain observer-based regulator to do so. The proposed result is demonstrated by numerical simulations, including a test based on a physical model relating to a real designed delta robot.

The insulators in operation are exposed to the air. Under the conditions of humid air (such as fog and drizzle), when they are seriously polluted, and the external insulation configuration is insufficient, the insulators will have pollution flashover, leading to a power failure of the line. UHV transmission lines feature large energy transmission and long distance. Once pollution flashover accident occurs, it will seriously threaten the stability of the power supply system [1]. Therefore, it is of great significance to determine the design of external insulation configuration of ultra high voltage project scientifically and economically. In this paper, the climatic environment, pollution source distribution and operating experience of nearby projects along the Sichuan-Chongqing transmission line are studied and analyzed. The AC pollution level is proposed. Through the research and analysis of insulator pollution test data of transmission lines along the Sichuan-Chongqing line, the key pollution accumulation characteristics of insulators in different environmental areas along the project, namely, the pollution ratio of top and bottom surface areas, are determined. The pollution flashover tests under different pollution conditions of top and bottom surface areas were carried out, and related pollution coefficients were obtained. According to the results of artificial pollution flashover voltage test of insulators, combined with the equivalent salt deposit density characteristics in Sichuan and Chongqing, the external insulation configuration under typical pollution conditions along the Sichuan-Chongqing UHV line was recommended.

The combined heat and power integrated energy system(CHP-IES) is considered to be an important development direction of the future energy system because it can supply energy with high proportion of renewables to the end-users in an efficient and independent manner. However, the operation of the CHP-IES is challenging due to the characteristics of strong multi-variable coupling and dynamic differences between thermal and electrical processes. Moreover, there are strong uncertain fluctuations in both the renewable sources and load demands. It is therefore important to develop advanced controllers to achieve the reliable and flexible operation of the CHP-IES. For this reason, this paper presents a multi-variable dynamic matrix controller (DMC) of the CHP-IES based on the dynamics of the system. Simulation results on an off-grid CHP-IES show that the DMC can track the heat and power demands with smaller overshoot and faster speed, thus can reduce the dependence of the system on batteries, compared with the conventional PID controller.

This paper presents an optimization model with strong universality, which involves the cost model of the VPP internal generator set, the VPP internal elastic load demand model, the maximum self-supply model and the maximum benefit model in the optimization objective of VPP. In order to further explore the influence of the uncertainty on the generation side when large-scale new energy is connected to the power grid, the influence of the characteristics of the aggregated DG inside VPP on the scheduling results is further analyzed. Finally, the VPP scheduling model is designed to study how to effectively decide the combined operation of internal pumped storage and energy storage batteries under the guidance of VPP's participation in the market price mechanism, so as to achieve the optimal goal. The model is based on the actual data, and the particle swarm optimization algorithm is used to verify the validity and rationality of the model.

As a power conversion interface for new energy generation into the power grid, grid-connected inverters are more and more widely used in modern power systems, and multiple inverters parallel technology has become one of the most mature technologies. When multiple inverters operate in parallel, droop control can be used to solve the problem of power sharing without relying on communication equipment. In order to ensure the stability of the inverter, three factors should be considered in the parameter design of the droop control, which are stability of drooping power outer loop, stability of voltage control double closed-loop and effects of current limiting on system stability. In this paper, the root locus method, bode diagram analysis method and simulation analysis method are used to theoretically analyze the stability problems caused by the above three factors. Meanwhile, the theoretical analysis is verified in Matlab/Simulink environment, which proves the correctness of the theoretical analysis.

With multiple types of demand-side flexible loads integrating to the distribution system (DS), demand side management is a way to improve the operation of the DS. Different types of flexible loads show different load characteristics and demand response performance. In this paper, the demand response strategy three types of representative flexible loads, i.e., electric vehicle charging stations, large industrial users with energy storage, and air conditioning clusters are established. Furthermore, an operation evaluation method for analyzing the impact of multiple types of flexible loads on DS is proposed. Finally, the proposed strategy and analysis method are validated on the modified IEEE-37 distribution network.

This article proposes a new neural network based adaptive model predictive control (named NN-AMPC) for power converters under load parameter uncertainties. Firstly, a supervisor MPC controller is designed for power converter using matched model parameters. Next, a NN is built and trained offline utilizing the operating information from the supervisor controller. A practical adaptive MPC controller using FPGA is then set up utilizing the trained NN to control the power converter online. The proposed NN-AMPC can adaptively track the variation of load parameters without extra identification process of load parameters. The dynamic response of the NN-AMPC under step changes in load parameters are analyzed and compared with conventional MPC. The concept of NN-AMPC is verified by experimental results on a 3-phase voltage source inverter (VSI) as the case study. It is shown that, the FPGA-based NN-AMPC controller offers better dynamic performance in the presence of uncertain parameters while utilizes reduced FPGA resource requirement compared with the observer based MPC controller.

Blast furnace gas-fired combined-cycle gas turbine (BFG-CCGT) is important in the steelmaking industry because it can convert the flue gas of blast furnace into electricity power in a highly efficient way. However, due to the large inertia, strong coupling and nonlinearity characteristics of CCGT, it has difficulties to achieve the ideal control effects. In addition, frequent fluctuations in the calorific value of BFG cause disturbances to the system, degrading the operating performance of the plant. It is thus urgent to develop advanced controllers to achieve flexible and reliable operation of the BFG-CCGT. For this reason, this paper develops a dynamic matrix control (DMC) with BFG calorific value feed-forward for the BFG-CCGT based on the understanding of system dynamic characteristics. Simulation results verify that the proposed DMC can effectively control the BFG-CCGT under variable working conditions and gas calorific value disturbances, providing fast and smooth tracking of the given set values.
