The Role of the ISO in U.S. Electricity Markets: A Review of Restructuring in California and PJM
نویسندگان
چکیده
Several regions of the U.S. have sought to restructure the electric power industry by separating the potentially competitive generation sector from the natural monopoly functions of electricity transmission and distribution. Under this restructuring scheme, a central authority, which we will refer to as the independent system operator (ISO), is given control over both the transmission system and the spot market for electricity. The ISO’s role in managing the spot market is relatively uncontroversial. This is because the spot market takes place in real time and requires continuous physical adjustments to electricity supply and demand subject to complex constraints, such as the need to maintain voltage and frequency within tight bands.

Geographic Integration, Transmission Constraints, and Electricity Restructuring
Abstract: We examine the impact on inter-regional trade in eastern U.S. electricity markets arising from the FERC-supported creation of Independent System Operators (ISOs). Our analysis focuses on the PJM ISO (Pennsylvania, New Jersey, Maryland, and other states) and its trade with the New York ISO and ECAR (East Central Area of Reliability). The formation of ISOs has been associated with two d...
متن کاملApplication of an Improved Neural Network Using Cuckoo Search Algorithm in Short-Term Electricity Price Forecasting under Competitive Power Markets
Accurate and effective electricity price forecasting is critical to market participants in order to make an appropriate risk management in competitive electricity markets. Market participants rely on price forecasts to decide on their bidding strategies, allocate assets and plan facility investments.

industry are often about the degree to which market relationships should replace transactions that formerly took place within regulated, vertically integrated utilities. Markets for the purchase of energy by vertically unintegrated distribution utilities are clearly feasible, but vertical deintegration of existing systems may eliminate some operational and reliability benefits that are importan...
متن کاملDifferentially Private Local Electricity Markets
Privacy-preserving electricity markets have a key role in steering customers towards participation in local electricity markets by guarantying to protect their sensitive information. Moreover, these markets make it possible to statically release and share the market outputs for social good. This paper aims to design a market for local energy communities by implementing Differential Privacy (DP)...
