Modified branch‐and‐bound algorithm for unravelling optimal PMU placement problem for power grid observability: A comparative analysis
Authors: Babu Rohit , Raj Saurav , Dey Bishwajit , Bhattacharyya Biplab
Published: April 2021

Safe operation of the power grid requires a complete and robust control network to ensure full observability. However, redundancy measurements can create problems in expense, management, and control. The optimal phasor measurement unit (PMU) positioning problem (OPPP) is proposed to limit the number of PMUs deployed in the power grid and ensure the whole grid's observability in the meantime. A modified branch‐and‐bound algorithm (MBBA) to unravel the OPPP is presented. Original BBA, which uses a single search order to create a binary tree, gives only one solution to the OPPP, although more than one optimal solution exists. The proposed MBBA method consists of two different stages: the vertexes in the search tree are investigated by depth‐first search (DFS) in stage 1, and the search route continues as the breadth‐first search. In stage 1, the LP relaxing problems are solved by dual simplex, and in stage 2, the basic viable solution from stage 1 is used to configure the primary simplex until the optimum solution is found. OPPP is formulated as a binary decision variable MBBA model, minimizing linear objective function subject to linear matrix observability constraints. The MBBA model is unravelled using a linear integer‐based external approximation scheme. IEEE test systems are used to check the feasibility of the proposed approach. Matlab software performs simulation based on a number of graph theory‐based methods such as DFS, graph‐theoretical method, simulated annealing, and recursive N‐algorithms. These algorithms are compared to the algorithmic perspective of the proposed MBBA method. IEEE test network results confirm the validity of the proposed methodology.
A comparative analysis between price‐penalty factor method and fractional programming method for combined economic emission dispatch problem using novel hybrid CSA‐JAYA algorithm
Authors: Dey Bishwajit , Basak Sourav , Bhattacharyya Biplab
Published: April 2021

Economic dispatch of power is no more a sole concern for utilities. Instead, the utilities focus on reducing toxic gases emitted to the atmosphere due to the maximum utilisation of conventional fossil‐fuelled generators to meet the surging demand for electricity. This can be carried out by involving renewable energy sources (RES) to generate clean power compensating the depletion in the availability of fossil fuels. This article performs combined economic emission disfpatch (CEED) on four dynamic systems with and without the involvement of RES. Two methods for solving CEED, namely the price‐penalty factor (ppf) method and the fractional programming (FP) method, are used to perform CEED for all the four test systems, and a comparative analysis between them is made based on the least emission of harmful and toxic gases into the atmosphere. A novel hybrid (CSA‐JAYA) algorithm is used as the optimisation tool for the study. Numerical results manifest that the FP method of solving CEED is economic and emits less toxic gases to the atmosphere than the ppf method. The proposed hybrid CSA‐JAYA outperformed a long list of algorithms from recent literature in consistently providing better and superior quality solutions.
The properties of the AGN torus as revealed from a set of unbiased NuSTAR observations
Authors: Zhao X. , Marchesi S. , Ajello M. , Cole D. , Hu Z. , Silver R. , Torres-Albà N.
Published: April 2021

The obscuration observed in active galactic nuclei (AGNs) is mainly caused by dust and gas distributed in a torus-like structure surrounding the supermassive black hole. However, the properties of the obscuring torus of an AGN in X-ray have not yet been fully investigated because of a lack of high-quality data and proper models. In this work, we perform a broadband X-ray spectral analysis of a large, unbiased sample of obscured AGNs (with line-of-sight column density 23 ≤ log(NH) ≤ 24) in the nearby Universe for which high-quality archival NuSTAR data are available. We analyzed the source spectra using the recently developed borus02 model, which enables us to accurately characterize the physical and geometrical properties of AGN-obscuring tori. We compare our results obtained from the unbiased Compton-thin AGNs with those of Compton-thick AGNs. We find that Compton-thin and Compton-thick AGNs may possess similar tori, whose average column density is Compton thick (NH, tor, ave ≈ 1.4 × 1024 cm−2), but they are observed through different (under-dense or over-dense) regions of the tori. We also find that the obscuring torus medium is significantly inhomogeneous, with the torus average column densities being significantly different from their line-of-sight column densities (for most of the sources in the sample). The average torus covering factor of sources in our unbiased sample is cf = 0.67, suggesting that the fraction of unobscured AGNs is ∼33%. We developed a new method to measure the intrinsic line-of-sight column density distribution of AGNs in the nearby Universe, and find the results to be in good agreement with constraints from recent population synthesis models.

Authors: Zhang Qiannan , Huang Yiyin , Bhuiyan Miraj Ahmed
Published: April 2021

Manufacturing industry is the leading industry in China’s national economy. The participation of global value chain (GVC) in China’s manufacturing industry is very high, whereas its GVC status is very low. The inward foreign direct investment (IFDI) and outward foreign direct investment (OFDI) are the main ways for China’s manufacturing industry to integrate into the global value chain. Previous studies mainly focused on the upgrading of GVC in China’s manufacturing industry from the perspective of single IFDI or single OFDI. This paper takes the perspective of “Two-Way FDI” as the starting point. Using the panel data of China’s manufacturing sub-industries, this paper analyzes the mechanism of IFDI, OFDI and two-way FDI influencing GVC. The Fixed Effect Model is established to analyze the impact of IFDI, OFDI and two-way FDI on GVC upgrading of China’s manufacturing industry.

Through the long-term interest rate model, the paper reveals the relationship between the circulation status of real economy and long-term interest rate. Based on the monthly data of China from 2003 to 2019, the paper establishes the error-correction VEC model and the state-space model to conduct empirical test and analysis on the influence mechanism of long-term interest rate. The final results show that exogenous factors such as monetary policy have certain influence on interest rate in the short run, while in the long run, interest rate is affected by the average circulation of goods described by the inventory increment of manufacturers and the actual production input of enterprises.

Authors: Yan Yunxi , Hu Shiyou
Published: April 2021

In the context of the great fluctuation of the global financial market, it is particularly important to forecast the changing futures market. Inspired by the utilization of the Heterogeneous Autoregressive model of the Realized Volatility (HAR-RV) model in price volatility forecasting, the parameters in this model could be a fair indicator of trading activities in the market. To test this hypothesis, this HAR-RV model is applied to analyze some representative commodities futures in China. The HAR-RV model is created to forecast the future volatility patterns using existed fluctuations. We used the least square method to do the regression analysis and used the volatility of a day, a week, and a month as the variables to get the degree of influence of each variable on the future volatility, namely. Thus, we can tell whether the price of a futures commodity is more affected by short-term fluctuations or long-term fluctuations by comparing different. Preliminary results show different patterns between iron ore and soybean meal futures models, pinpointing the trading frequencies in the corresponding markets. The price of iron ore futures is largely influenced by weekly volatility, while the price of soybean meal futures is affected significantly by monthly fluctuation.
Research on Real Estate Wealth Effect under the Background of Double Cycle Based on VAR Model
Authors: Tao Lina
Published: April 2021

In order to cope with the complex and severe development situation at home and abroad, in May 2020, the Party Central Committee proposed to accelerate the formation of a new development pattern with the domestic cycle as the main body and the mutual promotion of the domestic and international double cycles. Among them, the consumption of Chinese residents is a “double cycle” key part of strategy. From the perspective of consumption structure and property structure, real estate is an important part of household property and an important consumer object in China and it has a decisive influence on the effect of internal circulation. By constructing a real estate wealth effect model, this paper adopted the impulse response function method based on the VAR model, studies the changes in real estate prices, residents’ incomes, and residents’ consumption. The results show that the three interact with each other. In the long run, real estate has a positive wealth effect, but in the short term, there is a negative wealth effect, and consumers’ expectations of future housing prices will affect current consumption changes. In order to promote the domestic cycle, the author proposes to develop and improve the primary and secondary housing markets to ensure the liquidity of real estate, thereby stimulating consumption; guide residents to form healthy real estate price expectations, prevent large fluctuations in housing prices, and strictly stabilize consumption; the policy positioning of “no speculation” reduces the crowding-out effect of investment and speculative house purchases on residents’ daily consumption, thereby increasing consumption.
