Ministerstwo Energii oraz PSE S.A. reagując na potrzeby rynku energii w zakresie niepokrywania przez rynek kosztów stałych jednostek wytwórczych, opracowało projekt ustawy o rynku mocy. Mimo iż mechanizm ten swoim zakresem obejmie zasięg krajowy, będzie musiał otrzymać akceptację Komisji Europejskiej. Już w tym momencie można wskazać, że nieuwzględnienie wytwórczych zdolności importowych, wzbudzi...
This paper mainly focuses on the 5-minute resolution real-time price forecasting in New York electricity market. An accurate forecasting is regarded as a key to win the bidding in today's highly competitive electricity market. We propose a combination of support-vector machine (SVM) with self-organized map (SOM) to forecast the instance and magnitude of price spikes. The SVM is used for detecting...
This paper mainly focuses on the real-time price forecasting in New York electricity market through random forest. Accurate forecasting is regarded as the most practical way to win power bid in today's highly competitive electricity market. Comparing with existing price forecasting methods, random forest, as a newly introduced method, will provide a price probability distribution, which will allow...
This study aims to investigate the synergetic benefit of wind power and plug-in electric vehicles (PEVs) to the power system and to each other. We consider the integration of wind power and intelligent charging of PEVs into the wholesale electricity market of the New York Control Area (NYCA). We use a data-based two-settlement energy market model for the NYCA and a commuter transportation model for...
In electricity markets, traditional demand side management programs are slowly getting replaced with demand response (DR) programs. These programs have evolved since the early pilot programs launched in late 1990s. With the changes in market rules the opportunities have generally increased for DR for participating in emergency, economic and ancillary service programs. In recent times, various regulators...
Will the ldquomissing moneyrdquo in a competitive energy market be sufficiently addressed in the capacity market to garner adequate resources to keep the lights on? Can the capacity market provide economic signals to attract new investment in generation? A summary of how the New York Independent System Operator (NYISO) addresses these issues is discussed in this paper, along with a summary of the...
This paper presents a comprehensive study of forecasting a day-ahead of load and locational marginal pricing (LMP) using artificial intelligent systems. An artificial neural network (ANN) is trained with a stochastic optimization technique called particle swarm optimization (PSO). This training algorithm works to adjust the network weights and biases as to minimize the error function. Wavelet transformed...
The Joint Coordinated System Planning( JCSP) study has developed future transmission conceptual designs to serve the areas of the Mid west ISO, PJM , SPP including Energy, NE-ISO, NYISO, TVA, MAPP. The conceptual design includes multiple HVDC and EHV lines in an overlay. The HVDC communications, power control and control functionalities meld well with Wide Area Management System functions and goals...
By early 2009, roughly 60 % of the US capacity will operate in RTO markets. This panel session will discuss why a number of RTOs (NYISO, MISO, CAISO, and ERCOT) in the US are starting to use co-optimization to simultaneously clear energy and ancillary- service products.
Statistical and econometric modeling is used to analyze the dynamics of generators' bidding behavior and resulting market prices in the NYISO day-ahead market during the summer of 2001 at three levels. First, at the generator level, generators' offered capacity is modeled by a two-stage sample selection process. The grouping choices of generators are estimated in the first stage. In the second stage,...
Two electric utility control areas independently adapted existing system data collection software to capture the response of the units within their several utilities' generation before, during, and after the loss of large blocks of generation [ranging from 1000 MW to 2200 MW] during periods of otherwise normal operation. These measurements are essentially unannounced tests of the governing response...
The ongoing de-regulation of the U.S. electric power industry is to build open-access, non-discriminative and competitive electricity markets. In 2002 the federal energy regulatory commission (FERC) proposed Standard Market Design (SMD), in which the key is the locational marginal pricing (LMP) methodology to determine the energy price and to manage the network congestion. LMP has been adopted by...
This paper presents an update and extensions of New York Power Authority's (NYPA) harmonic measurement system (HMS) which has been deployed for over a decade. The HMS consists of hardware and software, which determine the harmonic state of a transmission system, in real time, and stores the acquired data in a historical harmonics database. The HMS hardware consists of global positioning system (GPS)-synchronized...
