Assessing Globalization's Critics: "Talkers Are No Good Doers???"

This paper is about the critics of the "doers" of globalization. It describes who they are, where they came from, what they want, how economists, policymakers, and others might understand them better, and where globalization might head from here. Many critics are themselves strongly internationalist and want to see globalization proceed, but under different rules. Some, particularly the protesters in the streets, focus mainly on what is wrong with the world. But some of them put forward broad alternative visions and others offer detailed recommendations for alleviating the problems they see arising from status quo globalization. Most of them have roots in long-standing transnational advocacy efforts to protect human rights and the environment and reduce poverty around the world. What brings them together today is their shared concern that the process by which globalization's rules are being written and implemented is undermining democracy and failing to spread the benefits broadly. This paper sketches the key issues and concerns that motivate the critics in a way that is broadly representative and intelligible to economists. It finds more resonance for the critics' agenda in economics than they commonly recognize. And it attempts to capture the concerns of Southern as well as Northern critics and to analyze the issues that divide as well as bring them together. Finally, it evaluates those issues and alternative proposals on which even globalization enthusiasts and the critics might come together cooperatively.globalization

Modified Differential Evolution Algorithm for Governing Virtual Inertia of an Isolated Microgrid Integrating Electric Vehicles

In modern power systems, there is a greater penetration of renewable sources, resulting in the expansion of microgrid. By implementing RES instead of conventional synchronous machines, the system’s overall inertia is significantly reduced. Modern and future power systems must reduce system inertia and keep the frequency at its nominal value since frequency oscillation impacts on the functionality, stability, and resilience of the system. Therefore, creating a stable, scalable, and reliable virtual inertia control system is crucial to effectively minimize the deviations during significant contingencies. Consequently, taking into account the probable issues, the foremost objective of this research work is to improve the dynamic security of an island microgrid through the implementation of a frequency control concept based on virtual inertia control. In the research study, the proposed microgrid system comprises of photovoltaics, wind-generating units, thermal power units, storage units, electric vehicles (EVs), and loads. A cascaded PIDFN controller is optimally designed using a novel metaheuristic modified differential evolution (MDE) algorithm that regulates the frequency based on virtual inertia control. In the MATLAB®/SIMULINK environment, various operating situations such as load variations, RES, and EVs disconnection are investigated, and the performance of the VIC-based MDE controller was compared to that of other controllers based on evolutionary optimization algorithms such as DE and TLBO. The results validate that the recommended virtual inertia control strategy enhances the reliability of the system
