New energy power system operation security evaluation based on the SWOT analysis

Abstract

Grid-connection of new energy is highly important in promoting the use of clean and renewable energy. However, it will bring huge risks to the power grid operation security, such as frequency stability, voltage stability, small signal stability, and transient stability, etc.,. In the study, SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis has been employed to construct 24 kinds of internal and external evaluation factors and 8 kinds of improvement strategies, for assessing operation security prospective with new energy power system of HM in China. The weights of SWOT factors are determined with the fuzzy-AHP method. Moreover, the fuzzy-MARCOS approach is used to select the most suitable strategies for power system operation security effective implementation. The reported research reveals that new energy in HM area not only has an ample potential for full development and generating electricity, but also brings operation security problems due to large-scale grid connection. Therefore, 8 kinds of improvement strategies are suggested to encourage the government to exploit and develop new resources, improve the investment pay, power generation and transmission technologies to mitigate the current energy crisis, and increase the energy security for sustainable development of the country. The methodology proposed herein is applicable with a case study concerning the operation security prospective of HM power grid, and all phases of the comparative analysis and sensitivity analysis illustrate the validity of MARCOS method. Furthermore, the ranked order of strategies is obtained as A2 > A6 > A5 > A1 > A8 > A7 > A4 > A3. The three most important strategies are A2, A6 and A5, i.e., “improving the technical establishment to encourage efficient and cheap electricity production”, “strive to build local permanent load, and reduce the risk of long-distance and high-capacity transmission”, “taking advantage of government incentives and investment to modify the irrational energy policies and energy planning”, respectively.

Planiranje energetske budućnosti grada: SWOT analiza – Studija slučaja grada Kragujevca

“…Dobro sprovedena SWOT analiza pruža uvid u moguće izazove budućnosti i, kao takva, može da posluži kao predmet budućih diskusija na nivoima donošenja odluka. Zbog svega navedenog, upotreba SWOT analize je široko rasprostranjena u polju energetskog sektora i korišćena je u radovima koji se zasnivaju na analizi energetskih sistema [14][15][16][17], održivog razvoja [18], razvoja i mogućnosti korišćenja određenih OIE [19][20][21], alternativnih goriva [22] i skladištenja energija [23], kao i energetskih politika i strategija [24,25].…”

Evaluating future strategies for sustainable growth of fiberglass composites industry in developing countries: A novel hybrid SWOT-Fuzzy extended PIPRECIA approach

“…SWOT analysis and fuzzy extended PIPRECIA can serve as a vital tool for the organizational development and can serve as useful information on external and internal factors which then help decision makers to select the best course of action according to study conducted by Popovic et al [ 18 ]. Energy planning, energy policy, technology evaluation, and sustainable energy are just a few of the many specific issues [ [19] , [20] , [21] , [22] ] that have been determined using SWOT analysis method over the years [ 23 ].…”

DOE-MARCOS: A new approach to multi-criteria decision making

“…This method has shown that it has significant advantages over other methods such as: the rank results of the alternatives are less dependent on the weight method, as well as the data normalization method [12]. Its advantages have been strongly taken recently: to evaluate resources in transport companies [13], to select equipment in logistics operations [14], to rank financial applications [15], to rank insurance companies and health care services [16], to select the best alternative for the process of powder-mixed electrical discharge machining (PEDM) [17], to assess logistics operations by drone [18], to select sustainable suppliers [19], to evaluate power system operation solutions [20], to review e-learning site [21], to take a solution for protecting the environment within the textile industry in Nigeria [22], to determine the effectiveness of railway systems in Africa [23], etc. However, like most other MCDMs, in the use of MARCOS method, scholars often consider ranking the available alternatives, not taking into account the case that there are alternatives arising in an implementation process.…”
