“…The structure of the two-region 6-node interconnected power system is shown in Figure 8. The line data and thermal power unit data are given in [53]. To ensure that the DC tie-line power flows from region A to region B , the load of region B was 1.2 times that of region A , and the consumption coefficient of the thermal power unit in region B was twice that of the unit in region A .…”

Aiming at the economic dispatch problem for an interconnected system with wind power integration, and in order to realize the goals of system economy and improvement of the cross-regional consumption level of wind energy, a decentralized coordination dispatch model is established in this paper. In this model, a DC tie-line is cut by the branch cutting method and used as a coupling variable. A virtual upper-level dispatch center is established, and the economic dispatch problem to be solved is decomposed into a master optimization problem for the upper-level dispatch center and subsidiary optimization problems for the lower-level dispatch centers. For solving this model, an improved Harris hawks optimization (HHO) algorithm called the chaotic mutation Harris hawks optimization (CMHHO) algorithm is proposed. In the CMHHO algorithm, tent mapping and the “DE/pbad-to-pbest/1” strategy are introduced, and a new nonlinear escape energy factor adjustment is proposed. Through an algorithm comparison experiment and a simulation experiment with two examples, the superiority of the CMHHO algorithm, the effectiveness of the proposed model and the applicability of the CMHHO algorithm to the proposed model are verified. The model proposed is of great significance for solving the economic dispatch problem for an interconnected system with wind power integration.

“…A design and demonstration of an islanded HRES with the optimal sizing for a remote school building in Bangladesh has been implemented for remote power supply and hospital maintenance. The optimal sizing approaches considered the meteorological data as well as fuel cost of that area for the diesel The effectiveness of the ED strategy in designing HRESs has been a topic of great interest lately [19][20][21]. Distributed or centralized control strategy can be utilized in solving ED related problems.…”

“…The electric power enterprises are under multiple pressures. How enterprises arrange capital investment is particularly important at present, certain research achievements have been made in investment effect evaluation methods, such as the establishment of post-evaluation system of economic benefit of technological transformation projects [1] [2] , the development of post-evaluation system of technological transformation overhaul [3] , efficiency evaluation model of overhaul project [4] , etc. Most of the research achievements are based on the "result-oriented" evaluation of the object's own investment effectiveness, and the overall investment efficiency cannot be considered.…”

Technological transformation input is one of the ways for electric power enterprises to expand and strengthen effective assets. It is of great significance to carry out structural analysis of multi-level technical transformation input in power grid under the background of national economic downturn and the deepening of power system reform. This paper combines the organizational structure relationship of a company in a province to build a multi-hierarchy structure tree, the attribute values of each node in the tree are defined, and the homogeneity and heterogeneity between nodes and between nodes are comprehensively and deeply analyzed by using correlation analysis, regression analysis, cluster analysis and other analysis methods. Meanwhile, the law of the change of attribute values of each node over time is studied. The variation rule of homogeneity and heterogeneity among nodes was analyzed, and the efficiency level of this company's investment in technological transformation in recent years was evaluated.
