Using solar, wind, geothermal, and hydroelectric as renewable energy generation instead of fossil fuel-based generation such as coal, oil, and natural gas, decreases greenhouse gas emissions in the electric power sector. Renewable energy plants present challenges for grid operators and are difficult to control because their output is based on variable natural resources and subject to intermittency and no predictability. Power grid operators need to be aware of how much renewable energy is being generated at any given moment, and how much renewable energy is expected. Therefore, the grid operators must allocate the needed generating capacity and properly balance supply and demand. Solar and wind power are examples of renewable energy sources that are neither constant nor regulated. Black-start capabilities, frequency responsiveness, control, autonomous generation control, and reactive power are a few technical and non-technical problems and obstacles to precise dispatching. In order to provide a comprehensive understanding of how renewable energy sources contribute to grid stability and introduce a macro-level understanding of how to interconnect them with the current network, this paper focuses on discussing the opportunities and challenges associated with renewable energy dispatching.
