Impact on transmission requirements of dispersed storage and generation. Final report

摘要: The objective of this study is to estimate the transmission and subtransmission credits dispersed power plants such as batteries fuel cells. Average credit a range for US were obtained by extrapolation based on two case studies using EPRI Synthetic Electric Utility Systems (EPRI EM-285, 1977). A conventional approach traditional utility planning criteria probabilistic which developed in Europe combined generation-transmission reliability program applied separately studies. networks are expanded first without devices then with devices. differences investments losses between expansions when properly discounted Energy limitation storage non-coincidence system local peak loads qualitatively reviewed regarding their effect credits. Study results indicate that overhead $66 $133 per kW installed capacity. In situations where underground cables could be deferred, high 250 $/kW.
